Silent applications

Navigation
1

Some applications, or most of them, have a silent or silent "silent install" option, which is to install an application without the user or support team needing interact with that application in your installation.

I started working on a third-party application, which has the following related permission: 

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

By default Eclipse issues the following error: 

Permission is only granted to system apps.

What should be considered when creating a silent app for Android outside the Google Play Store ? Why does this type of error occur?

The error informs that this permission can only be obtained by system applications.

To do this, the application must exist in Android ROM and be signed with the same key , or a rooted device installed in /system/app ( /system/priv-app API4.4 +) source

In order for Eclipse to stop issuing this error follow the steps source :

  

Window - > Preferences - > Android - > Lint Error Checking

Look for ID = ProtectedPermission in the list and set Severity for something other than error

If you want to install the app outside the Google Play Store , you do not need the android.permission.INSTALL_PACKAGES permission, just the device, where it will be installed, be configured to "allow unknown sources".

android.permission.INSTALL_PACKAGES permission is required for applications that install other applications.

  • In Eclipse:

    Window - > Preferences - > Android - > Lint Error Checking.

    • In the list find an entry with the id Protected permission . Set gravity to something more recent than error. This way, you can still compile the project using Eclipse.

  • In Android Studio

    File - > Settings - > Editor - > Inspections

    • Under the Android Lint option, find Using system app permission . Clear the check box or choose a lower severity than this error.
