I am using new device for testing named Samsung Galaxy SII but i am unable to use use debugging mode that means i am unable to see logs in my emulator but i am able to connect i
To debug applications on our android samsung galaxy S4, we must take steps like these, and I think it is also valid for the galaxy s2:
First we install the USB device drivers;
After the device must follow these steps:
1 - Select Apps
2 - Go to Settings
3 - Select More -> About Device
4-7 times on Tap Build Number
5 - Select More -> Developer options
6 - Check USB debugging
7 - Select OK to allow USB debugging
8 - Check USB debugging
