Question

Has anyone been able to successfully perform unit testing on the Android Emulator using methods offered by the TouchUtils class?
I m able to get the test(s) to pass on my device but when I run the exact same test(s) (and test suite) on an emulator, any test using a TouchUtils methods always throws the following exception:

java.lang.SecurityException: Injecting to another application requires INJECT_EVENTS permission
at android.os.Parcel.readException(Parcel.java:1327)
at android.os.Parcel.readException(Parcel.java:1281)
at android.view.IWindowManager$Stub$Proxy.injectPointerEvent(IWindowManager.java:1196)
at android.app.Instrumentation.sendPointerSync(Instrumentation.java:902)
at android.test.TouchUtils.drag(TouchUtils.java:786)
at android.test.TouchUtils.dragViewTo(TouchUtils.java:633)
...

I ve unlocked the keyguard and even ran other (non TouchUtils) test cases which have passed.
I do not have the @UiThreadTest applied nor am I running anything that requires code to run on the UI thread.
When I comment out the line that employs TouchUtils.dragViewTo(...) and put in a simple assert(true), the test runs and passes.

任何想法?

如果你的电话被锁定,或者在家中还有其他一些活动,就会出现这种情况。

The emulator is so slow, that when you emulate a UI interaction after you dismiss the virtual keyboard, there isn t enough time for the virtual keyboard to dismiss and so you are actually injecting events into the virtual keyboard and not your application.

在你躲藏软键板之后,在你试图进行任何“国际倡议”互动之前,就睡在你们的read子上约500-1000米。

try {
    Thread.sleep(500);
} 
catch (InterruptedException e) {
    e.printStackTrace();
}
