I'm trying to install programmatically an app without user interaction and i'm getting this error
SecurityException: Neither user 10057 nor current process has android.permission.INSTALL_PACKAGES
My installer is located in /system/app on rooted phone, "Install non market apps" is checked , 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'm getting this error

I have readed that ti is possible to gain INSTALL_PAKAGES permissions in two ways: signing the app with firmware's key or putting the app in the firmware. My app is runng from /system/app so it has to gain privileges.
Some one know what is wrong and give me some hints? Thanks
EDIT:
One step forward, two steps backward
i'we added new permission to the app
<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"/>
no more error
Neither user 10057 nor current process has android.permission.INSTALL_PACKAGES

Refer to signatureOrSystem permissions on custom ROM
Basically,
- add the required
<uses-permission> - push apk to /system/priv-app
Done (well, at least works for me).
You do not need to add android:protectionLevel="signatureOrSystem" or android:sharedUserId="android.uid.system". You could sign with any certification.
I assume that putting it in the /system/app folder is not equivalent to it being loaded in the firmware.
About the error:
SecurityException: Neither user 10057 nor current process has android.permission.INSTALL_PACKAGES
To get INSTALL_PACKAGES permission:
- Put your app in /system/app
- Sign the app with the system's key
In the manifest.xml file, put this attribute inside the tag manifest:
<manifest android:sharedUserId="android.uid.system" ...
Running these two lines fixes the issue with PackageManager permission error: "Couldn't create temp file for downloaded package file."
adb shell chown system.shell /data/app
adb shell chown system.shell /data/local
