Android Studio is not installing app into device
<p>My device is running android Lollipop 5.1 with Developers Options enabled and USB Debugging option checked. When I hit the RUN button on Android Studio it shows the following in the event log:</p>

<pre><code>Target device: qmobile-lt500-D5180B1R63091071
Installing APK: C:\Users\Umair\AndroidStudioProjects\MyApplication\app\build\outputs\apk\app-debug.apk
Uploading file to: /data/local/tmp/com.example.umair.myapplication
Installing com.example.umair.myapplication
DEVICE SHELL COMMAND: pm install -r "/data/local/tmp/com.example.umair.myapplication"
</code></pre>

<p>And then nothing happens. App doesn't install and open. When I click on Android Monitor, it shows events on logcat, my device name etc. confirming that it is properly connected.
Someone tell me where the problem is.</p>
