[UiAutomator] Permission denied when taking screen shot.

Hi,

I presume that with UiAutomator 2.0 the only way to invoke UI testing is using gradle ($ ./gradlew connectedCheck), however it seems like it doesn’t have enough privilege to create new file.

03-25 14:48:37.359: E/UiAutomatorBridge(13955): failed to save screen shot to file
03-25 14:48:37.359: E/UiAutomatorBridge(13955): java.io.FileNotFoundException: /data/local/tmp/uiautomator.png: open failed: EACCES (Permission denied)

But if you create the file via adb shell ($ adb shell touch /data/local/tmp/uiautomator.png) first then everything will works fine.

Could you please have a look on the gradle permission issue ?

Thanks, Dino

Hi. I found a decision.

1. You should add permissions in AndroidManifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

1. Input in console

adb shell pm grant com.example.android.testing.uiautomator.your_app android.permission.READ_EXTERNAL_STORAGE

adb shell pm grant com.example.android.testing.uiautomator.your_app android.permission.WRITE_EXTERNAL_STORAGE 3. And now you can take a screenshot

all above i have done .but can’t slove the problem
