从不受信任的UID呼叫 [英] Calling from not trusted UID

问题描述

当我在Android Studio中运行UIAutomator时，有时会显示崩溃.

When I was running UIAutomator in Android Studio, a crash shows sometimes.

 W/ActivityManager: Crash of app com.example.testsample running instrumentation ComponentInfo{com.example.testsample.test/android.support.test.runner.AndroidJUnitRunner}
07-16 19:19:34.191 7834-7850/? W/Binder: Binder call failed.
java.lang.SecurityException: Calling from not trusted UID!
    at android.app.UiAutomationConnection.throwIfCalledByNotTrustedUidLocked(UiAutomationConnection.java:427)
    at android.app.UiAutomationConnection.shutdown(UiAutomationConnection.java:324)
    at android.app.IUiAutomationConnection$Stub.onTransact(IUiAutomationConnection.java:209)
    at android.os.Binder.execTransact(Binder.java:570)

但并非每次都显示.如果没有显示，我可以成功运行.谁能帮我?谢谢.

But it didn't shows every time. I can run successfully when this not showed. Can Anyone help me? Thanks.

推荐答案

private void throwIfCalledByNotTrustedUidLocked() {
    final int callingUid = Binder.getCallingUid();
    if (callingUid != mOwningUid && mOwningUid != Process.SYSTEM_UID
            && callingUid != 0 /*root*/) {
        throw new SecurityException("Calling from not trusted UID!");
    }
}

这是引发错误的方法.也许 uid 与进程 uid 不同，或者该设备上的 uid 不是 root .也许您可以在您的应用程序中添加一些打印件以进行查找.

This is the method which throws your error. Perhaps the uid is different than the process uid or the uid on that device is not root. Maybe you can add some prints in your app to find out.
