How to solve it?

Check your drawable resource/images bundled. One of them or few of them might not be the proper .png files
AAPT: libpng error: Not a PNG file
Solution open the file which is not correct in an editor and save it with same name and correct .png extension.

You should comment org.gradle.parallel = true in gradle.properties.

react-native run-android failed with error: Execution failed for task ':app:dexDebug'

I'm using windows 8.1. with
react-native-cli: 1.0.0 and
react-native: 0.31.0
After adding react-native-maps to the project, I ran command react-native upgrade and given Y to all questions.
Then linked deps with rnpm link as well as come changes to MainApplication.java file too.
Here are changes to MainApplication.java:
// Other imports ...
import com.airbnb.android.react.maps.MapsPackage;
public class MainApplication extends Application implements ReactApplication {
private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
#Override
protected boolean getUseDeveloperSupport() {
return BuildConfig.DEBUG;
}
#Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new MainReactPackage(),
new MapsPackage() // I have added this for react-native-maps
);
}
};
#Override
public ReactNativeHost getReactNativeHost() {
return mReactNativeHost;
}
}
Now I'm getting error when I run the command: react-native run-android
λ react-native run-android

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html
I have no idea about this error. Saw some questions similar to this but could not find the answer. I'm new to React-Native and Android development so I'm having hard time understanding this stuff.

This problem usually comes from gradle dependency in new components, i can see you have installed react-native-maps
you can solve it by cleaning the project.
In your React Native project:
cd android/ && ./gradlew clean
go back and try run it again.
cd .. && react-native run-android

to be more specific:
in your MainApplication.java file, change,
protected boolean getUseDeveloperSupport() { { <-----
on this
public boolean getUseDeveloperSupport() { <-----
that got it building for me, at least

The problem for me was that, the packager was running in the background from the previous build.
You might just try to close the packager server and start it with
react-native run-android
That was successful for my problem.

Use these steps
1.) cd android
2.) gradle clean
3.) Now run the project.
This error occurs in my system whenever the emulator is updated.

just run this from root of your project with cmd:
cd android && gradlew clean

App won't build? DebugResources error?

Here is my problem
Can anyone help?
Ive tried changing the build version on gradle but it still doesnt run

Your log shows this:
AAPT err(Facade for 1220063698): libpng error: Not a PNG file
This means that somewhere you have an image resource that is not a PNG.
The log usually shows which file is causing the problem, but you might need to run with the --stacktrace option (e.g. gradlew assembleDebug --stacktrace).
If that still doesn't show the file name, you will need to look through your drawable folders for images that aren't PNGs.

Build -> Clean Project
Build -> Rebuild Project

make sure the images in your drawable is in png format.
you can convert any image in png format just by opening with a image editor and save as png.

I have searched to a good degree on stack overflow etc to try find an answer to my question. I have so far been unable to find any solution that works for my specific problem.
Up until the 5th of February, When I ran the command:
.\gradlew test
The command would complete and the build would be successful. Today (7th), I pulled changes from my teams remote repo. When I ran the command I would get the below output:

I created a new branch to see if I could figure out what commit was causing the issue, however, when I checked out a commit that I knew for certain did not contain issues (the commit I had previously been at) and attempted to run the command I would get similar output.
Similarly I used to be able to simply right click on my test file and select "Run whateverTest.java" and the test would run.
Now when I attempt the same thing I get the following output:

Now I must select the file and select "Run..." from the run tile. This will run my tests successfully.
I have attempted the ususal build, clean restart computer etc. I have also attempted to create a JAVA_HOME and ANDROID_JAVA_HOME environment variable (under recommendation of similar questions).
Since that time the only thing that sticks out to me is that there was a java update. I suspect this may be the cause but I am not certain.
I would appreciate any help and I can provide any more details that are required.
Thanks.
UPDATE
For more context here is more of the output from .\gradlew test
* What went wrong:
Execution failed for task ':app:compileDebugUnitTestJavaWithJavac'.
> Could not find tools.jar
Hopefully this gives better context.

SOLVED
Problem was solved by uninstalling both Java and Android Studio and then reinstalling them.
I believe there was a path hidden somewhere in Android Studio that I was unable to change that took a reinstall for me to be prompted to select.
