I developed an app recently and send it to a shop in our country called CafeBazaar to put it for sale but in an email they said:

we installed this app on Huawei P8lite with android 6.0 and we got
this error "Application not installed"

Now I searched a lot about this kind of error but this is very general error in my opinion and I can't determine how should solve this error

My manifest is like this:

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

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

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

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

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

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

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



 <meta-data

    android:name="firebase_crashlytics_collection_enabled"

    android:value="false" />

 <application

    android:name="com.android.example.example.AppController"

    android:allowBackup="true"

    android:hardwareAccelerated="false"

    android:icon="@mipmap/ic_launcher"

    android:label="@string/app_name"

    android:largeHeap="true"

    android:roundIcon="@mipmap/ic_launcher_round"

    android:supportsRtl="true"

    android:theme="@style/AppTheme"

I searched a lot but usually answer was put this two below attribute in your application tag on manifest:

• android:debuggable="true"


• android:testOnly="false"

I didn't done this yet but I want to know what should I do?

What worked for me was signing my app with both the signatures v1 and v2

You could try selecting one if you signed with both methods.

After several weeks of headache i finally find solution and i put it here so if anyone had same problem can solve it.

For this problem i putted this two attribute in application tag:

• android:debuggable="false"


• android:testOnly="false"
  
  
  

and finally it solved my problem.

<application

    android:name="com.android.example.example.AppController"

    android:allowBackup="true"

    android:debuggable="false"

    android:testOnly="false" 

    android:hardwareAccelerated="false"

    android:icon="@mipmap/ic_launcher"

    android:label="@string/app_name"

    android:largeHeap="true"

    android:roundIcon="@mipmap/ic_launcher_round"

    android:supportsRtl="true"

    android:theme="@style/AppTheme"
