I am quite new to app-development, and I ran into this problem after finishing my first app. Everything works fine when I launch it from android-studio, but when I build a release-apk and move it to my phone to install it (which works fine), I find no possibility to open it. The open button in the installing-screen is disabled and there is no entry in the app-menu on my phone. Here is my Manifest.xml, I hope that helps:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/Theme.AppCompat.NoActionBar"
    android:name="android.support.multidex.MultiDexApplication">
    <activity android:name=".activities.MainActivity"
        android:windowSoftInputMode="adjustResize">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
            <action android:name="android.intent.action.VIEW"/>
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="http"
                  android:host="@string/filter_title_rchat" />
        </intent-filter>
    </activity>
    <activity
        android:name=".activities.ChatActivity"
        android:label="@string/chatActivityHeader"
        android:windowSoftInputMode="adjustResize"/>


    <activity android:name=".activities.SignupActivity"/>
</application>

I found several people with a similar problem, however they all seem to have forgotten the 

            <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />

part. Also I read that multidex might be a reason for the problem, but in my research i did not find anything more specific on that.

Thank you for your time.

  • You did enable install from unknown sources? – ImAtWar Jun 01 '17 at 17:34
  • Yes it's enabled. I think otherwise i could not install it. – NotAName Jun 01 '17 at 17:34
  • Could you take a look at this? Might be similar problem https://stackoverflow.com/a/43491954/2725502 – ImAtWar Jun 01 '17 at 17:36
  • You should use release apk to post in the playstore, if you just want to use the APK you should build apk, and then you will get the app-debug.apk, which probably will work. –  Jun 01 '17 at 17:37
  • Try rebuilding after removing ` ` from your manifest. – Lal Jun 01 '17 at 17:37
  • I want to release the app, I just want to test the release-version before putting it into the playstore. I also tried a rebuilt apk after removing the named rows, it still cannot be opened. Edit: Installation still works, I just can't open it. – NotAName Jun 01 '17 at 17:42
  • I also saw the Question you mentioned before @ImAtWar, none of the answers worked for me. – NotAName Jun 01 '17 at 17:45
  • Can you install & use the debug apk? – ImAtWar Jun 01 '17 at 17:47
  • Yes, starting the debug apk works (at least from android studio) – NotAName Jun 01 '17 at 17:51
  • Try to put it as alpha or beta testing in your console developer account –  Jun 01 '17 at 18:09
  • I tried, to be completely honest thats how I realized it does not work and came to the understanding that release versions should be tested before the actual release :D – NotAName Jun 01 '17 at 18:12
  • Are you sure it is installed? Could you please check if the installer really says it is installed? Error message looks very similar to success message (if you don't expect it to fail then it's easy to miss the difference - I got caught by this a few times) – Markaos Jun 01 '17 at 21:01
  • Yes it is definitely installed. I just checked again. – NotAName Jun 02 '17 at 15:02
  • For everyone interested: I fixed it by moving ` ` into a different `` section. The suggestion @Lal made did not work for me though. Thank you for your answers. – NotAName Jun 02 '17 at 16:31
  • @NotAName That was what I too was telling.. ;) – Lal Jun 02 '17 at 16:38
  • Different i cannot be grouped, they must be seperated. I also had a problem like this with NDEF intent but thanks to your post, I have fixed it. – Winston Lycan May 19 '22 at 13:50
