title: Can't open installed app on android
body: <p>I have finished my application in Android Studio but when I copy and paste app-debug.apk on my android phone it can't be opened after installation. Can anybody tell me what is wrong a what I need to do to make that app run. Btw when I was writting the code I was running it on my phone through USB cable without using AVD. Here is my AndrodiManifest:

  <pre><code>&lt;application
      android:debuggable="true"
      android:allowBackup="true"
      android:icon="@drawable/ic_launcher"
      android:label="@string/app_name"
      android:theme="@style/AppTheme"&gt;
      &lt;activity
          android:name=".SplashActivity"
          android:label="@string/app_name"&gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.category.MAIN"/&gt;
              &lt;category android:name="android.intent.category.LAUNCHER"/&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
      &lt;activity
          android:name=".MainActivity"
          android:label="@string/app_name"&gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.category.MAINACTIVITY"/&gt;
              &lt;category android:name="android.intent.category.DEFAULT"/&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
      &lt;activity
          android:name=".InfoActivity"
          android:label="@string/app_name"&gt;
      &lt;/activity&gt;
