java.lang.SecurityException: Permission Denial: st

问题:

I get java.lang.SecurityException when try to startActivityForResult(intent, requestCode); with final Intent intent = new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS); intent. Interesting that this crash happens only on Huawei with Android 5.1 - 5.1.1 I haven't Huawei device. Could you please give me advice what it can be.

Stacktrace

回答1:

For whatever reason, Huawei left the <intent-filter> in place for this activity, but they marked it as not exported. There is no way that you can start the activity. All you can do is catch the exception and explain to the user that you cannot navigate there.

回答2:

According to android developer documentation.

In some cases, a matching Activity may not exist, so ensure you safeguard against this.
