I saw many topics regarding this error, but did not find a working solution. Therefore, I will try to fully describe the problem.
I have a project and a project test. My project manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.toto.app" android:versionCode="3" android:versionName="0.3.1"> ... <application android:icon="@drawable/icon" android:label="@string/app_name"> ... </application> </manifest>
And my test project manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.toto.app.test" android:versionCode="1" android:versionName="1.0"> <uses-sdk android:minSdkVersion="4" /> <instrumentation android:targetPackage="com.toto.app" android:name="android.test.InstrumentationTestRunner" /> <application android:icon="@drawable/icon" android:label="@string/app_name"> <uses-library android:name="android.test.runner" /> </application> </manifest>
Here is the activity I want to test: src / com / toto / app / activity / ListActivity, I have LaunchActivity (declared as a launch activity in the manifest) that trigger this action.
And in the test, my ListActivityTest is on the same path (src / com / toto / app / activity). I also tried using src / com / toto / app / test. A source:
public class ListActivityTest extends ActivityInstrumentationTestCase2<LaunchActivity>{ private Solo solo; public ListActivityTest() { super(LaunchActivity.class); } public void setUp() throws Exception { solo = new Solo(getInstrumentation(), getActivity()); solo.wait(2000); } }
LaunchActivity seems to be found, but when it starts ListActivity, I have an error:
% adb shell am instrument -w com.toto.app.test / android.test.InstrumentationTestRunner
com.toto.app.activity.ListActivityTest: INSTRUMENTATION_RESULT: shortMsg = java.lang.ClassNotFoundException INSTRUMENTATION_RESULT: longMsg = java.lang.ClassNotFoundException: com.toto.app.activity.ListActivity in the loader of the system class /android.test.runner.jar:/data/app/com.toto.app.test-2.apk:/data/app/com.toto.app-2.apk]
I don’t understand why one class is found and the other is not ... In Eclipse, it doesn’t work the same way. I tried using ListActivity directly in the test folder, but the same error. How does he create this apk to avoid some class?
This is a full stack when using adb.
Full stack in logcat eclipse:
