[Solved] Android/sdk/build-tools/llvm-rs-cc finished with non-zero exit value 1

When I try to compile my renderscript application I see this error "llvm-rs-cc.exe finished with non-zero exit value 1" on my Windows PC in Android Studio IDE. And when I try to run the same project on Mac OS X , I face this same error "Android/sdk/build-tools/llvm-rs-cc finished with non-zero exit value 1".

I searched and read through too many web pages and documentation, then found that the error is appearing because the API version of renderscript is old. So I used the latest API version of renderscript which is 24 at my project time.

Use Latest Renderscript API Version

As you can see in the image, I set the renderscriptTargetApi version to 24 and the error of llvm-rs-cc error is disappeared.

[Solved] Cause: error=86 , Bad CPU type in executable - RenderScript App in Android Studio on Mac OS X

I faced this error "cause: error=86 , bad cpu type in executable" when I tried to run my Android application. This app is using render script and I use Mac OS X to run Android Studio IDE. I fixed this error in a crazy amount of time. Let's take it step by step to fix the error for you as well.

Check For Updates

Just check for updates of Android Studio IDE. Update it if there is any updates. Then rebuild the project form the build menu.

If the error still showing up, try the next fix.

Disable The Support Mode for RenderScript

One of the craziest fixes I've ever seen. Just disable the support mode for renderscript as you can see in the following image.

When you disable this support mode, the renderscript works. That's insane. Just set "renderscriptSupportModeEnabled" to "false".

If still the error showing up in the console.

Use Support Library instead of AndroidX

I used androidx libraries but it doesn't work, so I changed it to the old support library for renderscript and it worked fine. The normal support library is "android.renderscript.*" as you can see in the following image.

After those three steps, my renderscript project worked fine. I never seen the bad CPU error again. I hope it works for you too. If you recommend reading this fix, share it on social media. If you want to get new posts, make sure to subscribe to Value In Brief by Email.

Say it's not a time for chatting.. it's a business hour, so keep working and we'll talk later.

Chatting with your friends at work consume your time, and energy.. then your day is off and your energy is gone!

Keep working in a smart way and close any long-chatting with friends.

10. Too many meetings

Meetings are useful for your business?

Yes, but keep it short and smart! How?

Making long-meetings consume up your time and energy, not only your time but also your employees time and energy.

So the solution is to think about the meeting, the targets of it, who attend. After planning for this meeting in a short time, meet them and focus on how to achieve the most from this meeting.

Save up your time and effort to improve your business! that's the smart idea.

11. TV : television

Turn off TV.. It's a life-consuming not a time-consuming!

Everything waste your precious time, keep yourself away from it! that's the smart strategy to avoid wasting time.

12. Taking calls from friends during business hours.

Don't call friends during the business hours. The great strategy for phone calls is:

• Cancel all non-useful calls.
• Keep phone calls as shorter as you can.

Keep up the good work! and avoid wasting time.

13. Chasing the big account that you think will change your life instead of the small sales.

If I have that, I would have a great deals! if I was at this time, I would have something great! if.. if.. and if.

Thinking of opportunities which you don't have really is a great waste of time. Thinking of those if's will make you lose hope and work-time.

Think smart, and keep your time and energy for work. Improve your business, that's all!

14. Reading the wrong books.

Reading is a great behavior! Reading books is a pleasure! really I love it!

What to read is the key? and When to read is the other key?

Read books which give you useful ideas and information for you business. Don't waste your time reading a ridiculous book!

Read as many books as you want BUT focus on your business field.

15. too much partying.

Parties are great events to have fun! But keep going to parties all the time is a bad habit to waste your time.

Keep it for important events and parties only. Keep working with smart methods all the business hours of the day. Then make a time for partying each week or month.

Final Tips!

How to Fix DNS Server Not Responding Problem Error

Are you running into DNS errors when you try to load a website or connect to your network? The Domain Name Server (DNS) is a server that translates website's addresses so that your browser can connect to them. Occasionally, you can lose connection to the server, through either corrupt settings or problems on the server's end.

Here's three main steps to fix this error :

1. Verifying Your Connection
2. Troubleshooting the Computer
3. Troubleshooting the Router

You can watch a video for the fix here :

1. Verifying Your Connection

- Connect another device to the network.

Before you begin trying to solve the issue, it will help to know where the issue is occurring. You can narrow down the problem by performing a few quick tests. Connect another device to your router, either wired or wirelessly.
You can use another computer, or a smartphone or tablet. Anything that accesses the internet will work to test.

- Try to access a webpage from the second device.

If you are still receiving DNS errors, then the problem lies in your router or with your ISP. If you can connect to the website, then the problem is coming from the first computer.

- Power cycle your modem and router.

Unplug your modem's power cable as well as your router's power cable. Allow them to sit unpowered for at least 30 seconds so that any residual charge is released and the memory is cleared. Reconnect your modem, and wait for it to fully connect. After it has powered on completely, reconnect the power cable to your router and allow it to boot up. This could take up to a minute.
Once you have power cycled both devices, try connecting to a website again. If the problem still persists, move on to the next section.

If you're using a mobile device you can go to >settings>mobile data and reset the configurations.

2. Troubleshooting the Computer

- Try a different browser.

This is one of the quickest ways to test your DNS connections. Download a different free browser such as Firefox or Chrome and attempt to connect to the internet. If the issues persist, then the problem is likely not with the browser, but with some other setting on the computer.
If the issues are resolved, then you can try troubleshooting your old browser. Oftentimes the issue stems from the proxy settings.

- Disable any extra connections.

Occasionally, Windows will install extra connections that you won't normally use. For best connectivity, you should only have the connections that you use regularly enabled. To open your Network Connections window, click the Start menu or press the ⊞ Win button and search for "ncpa.cpl".
Look for extra connections. You should see a list of all your connections. The most common cause for DNS issues is the existence of "Microsoft Virtual WiFi Miniport Adapter". IF you see this, right-click it and select "Disable".
Test your connection again. Wait a few moments and then open your browser again. Try to visit a website. The DNS may take a few moments to load, but if the webpage appears then the problem has been solved. If not, move on to the next step.

- Flush your DNS.

Sometimes your DNS cache gets outdated and needs to be manually flushed. This can be done from the Command Prompt.
To open the Command Prompt, press ⊞ Win+R and type cmd.
Type ipconfig /flushdns. Wait for the command to process and then restart your computer.
Test the connection again. If the problem still persists, move on to the next step.

- Change your DNS server.

You can manually enter an alternative DNS server to attempt to connect to instead. To do so, open the "ncpa.cpl" window again and right-click on your active connection. Select "Properties".
In the Networking tab, scroll down until you find the "Internet Protocol Version 4 (TCP/IPv4)" entry. Click it to select it and then click the Properties button.
Click the "Use the following DNS server addresses" option.
Enter 208.67.222.222 into the "Preferred DNS server" field
Enter 208.67.220.220 into the "Alternate DNS server" field.
These are DNS servers maintained by OpenDNS, an open-source DNS service.

- Try connecting in Safe Mode.

Rebooting your computer into Safe Mode will only load the essential files for Windows, which will allow you to determine if another program or service such as your antivirus is causing the connection issues.
You can try disabling your antivirus first and seeing if that fixes the issue. If so, then you should uninstall your antivirus and install a new one.
Reboot your computer and hold down the F8 key while it is booting up.
Select Safe Mode with Networking from the list of options.
Test the connection. If you are able to successfully connect to the internet, then the problem lies with a program running on your computer. Examine the startup files and disable programs until you find the culprit.

3. Troubleshooting the Router

- Plug your computer directly into your modem.

If you are using a router to create a home network, disconnect your computer from it and plug an ethernet cable directly into your modem's Ethernet port.
Attempt to load a webpage. If you are still receiving DNS errors, then the problem likely lies with the ISP. Contact them and inquire about connecting to the DNS servers.
If you can connect to a web page, then the problem stems from your router. Reconnect your router to your modem and connect your computer back to the network to continue troubleshooting.

- Enter in alternate DNS servers.

You can change your router's settings so that it attempts to manually connect to alternate DNS servers. This can tell you if your ISP's DNS server may be faulty.
Open your router's configuration page. This is different for every router, but essentially you will need to enter your router's IP address into your browser's address bar. See this guide for more details.
Open the Internet section. Find the subsection marked "Domain Name Server (DNS) Address".
Set it to manually use DNS servers that you enter.
Enter the OpenDNS server information (Primary - 208.67.222.222, Secondary - 208.67.220.220) or Google DNS server information (Primary - 8.8.8.8, Secondary - 8.8.4.4).
Click Apply or Save Changes. Your router will take a few moments to apply the changes.
Test it out. Open up a new browser window on your computer and attempt to connect to a website. If you are able to connect then your ISP is most likely having DNS issues.

- Reset your router.

Sometimes the settings on your router might get corrupted, and the easiest way to fix them is to simply reset your router to default settings. This will reset your wireless network settings and any port forwarding information.
To reset your router, use a paperclip or other pointy object to press and hold the Reset button on the back of the router.
Reconfigure your router. After it has been reset, you will need to reconfigure your wireless network (if you were using it). Any admin passwords and accounts will be reset as well.

5 ways I avoid procrastination

Almost all of us face procrastination. We suffer from procrastination in too many things especially when it comes to a huge task or project. Starting a new project is sure a procrastination! Feeling overwhelmed with the task or project leads to procrastination. Make it later. Start it tomorrow! I am not in the mode! I am feeling not OK. I'll sure begin the project tomorrow.

All of these things are our procrastination strategy. This is a bad behavior which we all fall in. In this blog post I will show you how I overcome the procrastination. I can cancel procrastination by these ideas.

1. finding a proper 'why'

If you can't find a good reason to start that project/task, you will never start it. So, write down your goals! find a reason that you really want to achieve. If there is no reason for the project, so don't bother trying to achieve it.

If you found a proper goal for the project, draw the most efficient route to your destination to your goal. So you can achieve your goal and do the project as you want.

2. set alarms

We always forget the time passed. Entertainment can make hours seem as a minute to us. So remind yourself of time passing. Set alarms for each thing you do. Set alarm for gym. Set alarm for eating. Set alarm for social media. Set alarm for doing something on your smartphone. Make your life a little bit organized by setting alarms for each and every activity you do. So you can make sure you start and stop that activity on time.

4. change your environment / surroundings & pinpoint your weaknesses

Try to change your environment, then find if it makes you more productive. Changing surroundings makes you in a different mode. Try to find what makes you less productive. Track your time and activities which makes you more or less productive.

Get rid of the activities that make you less productive, or at least give that activity less time with strict alarms.

Give more time for the activities that make you more productive. Find what drives your productivity, and follow it.

5. breaks things down

Starting a huge project is a procrastination candidate. You must break down that project to small parts and start with a teeny tiny part. After completing the first part, work on the next part.

Breaking down big tasks into small ones, helped me achieve too many goals in my life. I am a software developer. I created more than 100 Android apps, and more than 10 websites in different technologies / tech stack.

I am done with avoiding procrastination. If you want to get new posts, make sure to subscribe to Value In Brief by Email.
