android – 通过/ system / app的INSTALL_PACKAGES许可,以编程方式安装应用程序

我正在尝试以编程方式安装一个没有用户交互的应用程序,我收到此错误

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

我的安装程序位于/ root / root系统/应用程序,“安装非市场应用程序”被检查,安装程序有权限

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

这是我的通话功能

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;
        }
    }

}

我收到这个错误

我已经阅读了ti可以通过两种方式获得INSTALL_PAKAGES权限：用固件的密钥签署应用程序或将应用程序放在固件中.我的应用程序是从/ system / app运行,所以它必须获得权限.

有人知道有什么错,给我一些提示？谢谢

编辑：

向前一步,向后两步

我向应用添加了新的权限

<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"/>

没有更多的错误

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

但新的

使我的手机崩溃,freez并重新启动

解决方法

参见 signatureOrSystem permissions on custom ROM

基本上,

>添加所需的< uses-permission>
将apk推送到/ system / priv-app

完成了(至少对我而言).

你不需要添加android：protectionLevel =“signatureOrSystem”或者android：sharedUserId =“android.uid.system”.您可以签署任何认证.
