Problems installing programmatically an application with INSTALL_PACKAGES permission from / system / app

Question

I try to install the application programmatically without user interaction and I get this error

SecurityException: Neither user 10057 nor current process has android.permission.INSTALL_PACKAGES 

My installer is located in / system / app on the root phone, the "Install non-market applications" checkbox is selected, the installer has permission

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

This is my call function.

  private void puk(Context context) throws IllegalArgumentException, IllegalAccessException, InvocationTargetException{ String fileName = PAKAGE_FILE_NAME ; String dir_type = Environment.DIRECTORY_DOWNLOADS; File dir= Environment.getExternalStoragePublicDirectory(dir_type); java.io.File file = new java.io.File(dir ,fileName); Uri packageUri = Uri.fromFile(file); PackageManager pm = context.getPackageManager(); Class<? extends PackageManager> o = pm.getClass(); Method[] allMethods=o.getMethods(); for (Method m : allMethods) { if (m.getName().equals("installPackage")) { Log.e(TAG, "installing the app.." ); m.invoke(pm,new Object[] { packageUri, null, 1, "com.mic.zapp"}); break; } } } 

I get this error

I read that ti can get INSTALL_PAKAGES permissions in two ways: sign the application using the firmware key or put the application in the firmware. My application starts from / system / app to get privileges.

Does anyone know what is wrong and give me some advice? Thanks

EDIT:

One step forward, two steps back

I added a new permission for the application

  <permission android:name="com.mic.pvtapi.permission.INS_AP" android:label="etichetta_perm" android:protectionLevel="signatureOrSystem" /> <uses-permission android:name="com.mic.pvtapi.permission.INS_AP"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

 Neither user 10057 nor current process has android.permission.INSTALL_PACKAGES

make my phone crash, freez and reboot

Answer 1

Refer to signatureOrSystem authority on user ROM

Basically,

• add the required <uses-permission>
• push apk to / system / priv-app

Done (well, at least it works for me).

You do not need to add android: protectionLevel = "signatureOrSystem" or android: sharedUserId = "android.uid.system". You can sign up with any certification.

Answer 2

I assume that placing it in the / system / app folder is not equivalent to downloading it to the firmware.

Answer 3

About the error:

 SecurityException: Neither user 10057 nor current process has android.permission.INSTALL_PACKAGES 

To get INSTALL_PACKAGES permission:

• Put your application in / system / app
• Sign the application using the system key

• In the manifest.xml file, place this attribute inside the tag manifest:

   <manifest android:sharedUserId="android.uid.system" ... 

Answer 4

Running these two lines resolves the problem with the PackageManager permission error: "Failed to create temp file for downloaded package file."

 adb shell chown system.shell /data/app adb shell chown system.shell /data/local
