BluetoothPermissionActivity and DevicePickerFragment will send broadcast to return the result to calling apps. As this broadcast intent is from Settings with uid 1000, it will be sent to any protected BroadcastReceivers in the device. It can make an attacker send broadcast to protected BroadcastReceivers like factory reset intent (android/com.android.server.MasterClearReceiver) via BluetoothPermissionActivity or DevicePickerFragment. This CL will compare to calling package name with launch package name. If they are not equal, the broadcast will not send to launch package name. Bug: 179386960 Bug: 179386068 Test: make -j42 RunSettingsRoboTests and use test apk to manually test to verify factory reset not started and no system UI notification.
