Android Gradle Project upgrading build tools to 21.0.1: aapt throws Exception

We have an android gradle project. Today I wanted to upgrade the android build tools version from 20 to 21.0.1, but now the aapt is failing.

* What went wrong:
Execution failed for task ':myproject-android:processDebugResources'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
c:\_DEVELOP\AndroidSDK\sdk\build-tools\21.0.1\aapt.exe package -f --no-crunch -I c:\_DEVELOP\AndroidSDK\sdk\platforms\android-16\android.jar -M D:\_MY_PROJECT\trunk\myproject_bin\gradle\build\re

myproject_bin\gradle\build\release\myproject-android\intermediates\symbols\debug
Error Code:

I had some warnings saying:

libpng warning: iCCP: Not recognizing known sRGB profile that has been edited


I fixed those, but there are 6 more in the appcompat-v7 library.

If I revert the build tools version to 20 everything works fine.

Has anyone came across this problem?

Answer

This is caused by a faulty aapt. There was a similer problem in 21.0.0 too (Error Code: -1073741819). You need to update build-tools again to fix it.

  • Open sdk manager and install build-tools 21.0.2.

  • Then change your build.gradle so that it looks like this.

    apply plugin: 'com.android.application'
        android {
            compileSdkVersion 21
            buildToolsVersion "21.0.2"
    

Replace version numbers with the most recent ones as necessary.
