We have a rather unique situation with our Android project, in that we use
the same code base to build literally thousands of different apps, each
with a different package name.
For the most part this hasn't been a problem. Recently I migrated our build
system to Gradle and it is certainly functional, but we don't seem to be
able to take advantage of some of the benefits of Gradle 2.0, specifically
incremental builds and instant run.
NOTE: I am thinking these 2 issues are related, since if the correct
package name is cached, incremental builds and instant run work fine.
1) For some reason, ALMOST every build I run cleans itself before it runs,
even when no source is changed.
Executing tasks: [:app:clean, :app:generateDebugSources, :app:
mockableAndroidJar, :app:prepareDebugUnitTestDependencies, :app:
generateDebugAndroidTestSources, :app:assembleDebug]
I'm assuming this is Gradle getting confused, but I have no idea how to
troubleshoot what might be causing a clean to be triggered.
2) And this is completely tripping me out. I will build my app with this
package name, and ADB installs it correctly:
*com.subsplash.thechurchapp.aaronchurch*
But it seems Android Studio caches the old one for a very long time, which
results in an error like this...
$ adb shell am start -n
"*com.subsplash.thechurchapp.freshlifechurch*/com.subsplash.thechurchapp.SplashActivity"
-a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Error while executing: am start -n "
*com.subsplash.thechurchapp.freshlifechurch*/com.subsplash.thechurchapp.SplashActivity"
-a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Starting: Intent { act=android.intent.action.MAIN
cat=[android.intent.category.LAUNCHER]
cmp=com.subsplash.thechurchapp.freshlifechurch/com.subsplash.thechurchapp.SplashActivity
}
Error type 3
Error: Activity class
{*com.subsplash.thechurchapp.freshlifechurch*/com.subsplash.thechurchapp.SplashActivity}
does not exist.
Error while Launching activity
I have searched my whole machine for the text:
com.subsplash.thechurchapp.freshlifechurch
And I can't find it anywhere. I have purged caches, removed all build
files, and the Android Studio preferences. Does anyone know where Android
Studio is getting this package name from?
Also, quick note on how I am providing the package name. In build.gradle I
am reading the package name from an API endpoint, and I am generating the
Android manifest conditionally if the package name changes.
json = new JsonSlurper().parseText(proc.text)
androidPackageName = json.android.package_name
android {
compileSdkVersion 'Google Inc.:Google APIs:23'
buildToolsVersion "23.0.2"
useLibrary 'org.apache.http.legacy'
defaultConfig {
applicationId androidPackageName
minSdkVersion 10
targetSdkVersion 22
versionName project.tcaVersion
}
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = [project.SRC_DIR]
res.srcDirs = [project.RES_DIR]
assets.srcDirs = [project.ASSET_DIR]
aidl.srcDirs = [project.SRC_DIR]
renderscript.srcDirs = [project.SRC_DIR]
}
