Do you android.content.res.Resources$NotFoundException: unknown resource ? (aka Testing with Robolectric (II))
I assumed that one only needed to specify the location of the manifest if, like here, you were extending the Application class. After reading and failing miserably to get the most stupid test up and running, turns out that when you have BuildTypes and/or Flavours you have to explicit about your manifest too.
So if you are getting one of these pesky exceptions:
Double check that you specify the location of your AndroidManifest file in the

Testing with Robolectric (I)
If you have your own Application class for your Android app, you might have found your tests failing because of a class cast exception:
You can annotate also annotate the whole suite.
java.lang.ClassCastException: android.app.Application cannot be cast to BLALBLA classAnd if you are using Robolectric 2.+ the way to solve this is to annotate your test with
@Configlike so:

Get Google Play services in your app (Intellij Android Studio)
You can find an easy way to get Google Play services in your project here
But for an even easier way, this is your safest bet
UPDATE:
If you change update your Studio, make sure to run a clean and build. Wasted morning N+1

Running tests Test running startedTest running failed: Unable to find instrumentation info for: ComponentInfo{ [package.name]/android.test.InstrumentationTestRunner} Empty test suite.
I have been trying to run tests using Intellij's Android Studio. So I started here and used the IDE to help me create everything I needed. Failed horribly. Then I followed this and kept receiving this HELPFUL message:
like a billion times!
These are the things I have learnt:
This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.

like a billion times!
These are the things I have learnt:
- Android/Studio use JUnit 3 so the constructor for your test suite MUST NOT have any parameters (aka don't let Studio create a constructor for you because it will add a parameter and JUnit will not be able to find your test suite):
- Your test needs to be in:

Android Studio (Intellij) can't find aapt...but it's there!!! (UPDATED)
UPDATE: I have also encounter this with the following error message (it can be fixed the same way or following this):
db: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
If you are having problems with Android Studio (Intellij) when trying to run it for the first time with a message like:
android-apt-compiler: Cannot run program "PATH/TO/android-sdk-linux/platform-tools/aapt": java.io.IOException: error=2, No such file or directory
db: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

android-apt-compiler: Cannot run program "PATH/TO/android-sdk-linux/platform-tools/aapt": java.io.IOException: error=2, No such file or directory
I found this (basically create symbolics links to the actual place where the files are. Didn't do anything for me) and THIS which actually fix it for me.
Turns out, as you can clearly read from the error message, it was a architecture problem. Aapt expects 32 bit binaries and my desktop is 64 bits.

With a nice:
apt-get install ia32-libs
it should work
