If I run gradle assembleDebug
from the command line, I am suddenly getting this error:
UNEXPECTED TOP-LEVEL EXCEPTION:

If I grep for v4 I see two files inside my build folder.
Binary file build/pre-dexed/debug/support-v4-19.0.0-2ba5fdd60a6c3836b3104a863fe42897da1fa9d1.jar matches
Binary file build/pre-dexed/debug/support-v4-r7-227d905d79b23b20866531d4f700446c040a2ccb.jar matches
My gradle file includes only this support library:
compile 'com.android.support:support-v13:19.0.0'
I am stumped as to how the r7 library is included somehow. I've run gradle clean
and it always appears there when I rerun assembleDebug.
If I grep for r7 inside the build directory, I see it inside the file:
Binary file build/exploded-bundles/ComGoogleAndroidGmsPlayServices4030.aar/classes.jar matches
If I don't include v13, then other things don't compile.
But doesn't v13 include v4 support library?
Is this an incompatibility between play services AAR bundle and the v13 library?
I grabbed the gradle file from gradleplease.appspot.com.
Removing play services does not fix it; same error.
My dependencies inside build.gradle:
dependencies {
// Google Play Services
//compile 'com.google.android.gms:play-services:4.0.30'
// Support Libraries
//compile 'com.android.support:support-v4:19.0.0'
///compile 'com.android.support:appcompat-v7:19.0.0'
//compile 'com.android.support:gridlayout-v7:19.0.0'
compile 'com.android.support:support-v13:19.0.0'
compile 'org.eclipse.mylyn.github:org.eclipse.egit.github.core:2.1.5'
compile 'commons-codec:commons-codec:1.9'
compile 'com.madgag:markdownj-core:0.4.1'
compile 'com.wu-man:android-oauth-client:0.0.2'
compile 'com.google.http-client:google-http-client-jackson2:1.17.0-rc'
compile 'org.apache.commons:commons-lang3:3.2'
compile 'com.google.code.gson:gson:2.2.4'
}
Run gradle -q dependencies
(or gradle -q :projectName:dependencies
) to generate a dependency report. You should see where r7
is coming from, such as:
compile - Classpath for compiling the main sources.
+--- com.commonsware.cwac:camera-v9:0.5.4
| +--- com.actionbarsherlock:actionbarsherlock:4.4.0
| | \--- com.google.android:support-v4:r7
| +--- com.commonsware.cwac:camera:0.5.4
| \--- com.android.support:support-v4:18.0.+ -> 18.0.0
\--- com.android.support:support-v4:18.0.+ -> 18.0.0
Then, use the exclude
directive to block that dependency. In my case, it is coming from my CWAC-Camera library, and so I use:
dependencies {
compile('com.commonsware.cwac:camera-v9:0.5.4') {
exclude module: 'support-v4'
}
compile 'com.android.support:support-v4:18.0.+'
}
(where the second compile
statement indicates what version you actually want)
That should clear matters up, as you will see if you run the dependency report again:
compile - Classpath for compiling the main sources.
+--- com.commonsware.cwac:camera-v9:0.5.4
| +--- com.actionbarsherlock:actionbarsherlock:4.4.0
| \--- com.commonsware.cwac:camera:0.5.4
\--- com.android.support:support-v4:18.0.+ -> 18.0.0
