Hi Dianne, I have tried to annotate the test method with UiThreadTest, but still it doesn't work, the trace log is: java.lang.RuntimeException: This method can not be called from the main application thread at android.app.Instrumentation.validateNotAppThread (Instrumentation.java:1500) at android.app.Instrumentation.waitForIdleSync(Instrumentation.java: 397) at com.liufeng.vehicle.test.BikeTests.testBikeButton(BikeTests.java: 45) at java.lang.reflect.Method.invokeNative(Native Method) at android.test.InstrumentationTestCase.runMethod (InstrumentationTestCase.java:191) at android.test.InstrumentationTestCase.access$000 (InstrumentationTestCase.java:36) at android.test.InstrumentationTestCase$2.run (InstrumentationTestCase.java:171) at android.app.Instrumentation$SyncRunnable.run(Instrumentation.java: 1538) at android.os.Handler.handleCallback(Handler.java:587) at android.os.Handler.dispatchMessage(Handler.java:92) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:3948) at java.lang.reflect.Method.invokeNative(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run (ZygoteInit.java:782) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:540) at dalvik.system.NativeStart.main(Native Method)
So what's the problem? And is there any other method I can use to perform a call on UI thread?
