我正在尝试在没有用户交互的情况下以编程方式安装应用程序，但出现此错误
SecurityException: Neither user 10057 nor current process has android.permission.INSTALL_PACKAGES
我的安装程序位于 root 手机上的 /system/app 中，选中“安装非市场应用程序”，安装程序具有权限
<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;
}
}
}
我收到此错误

我已经读过 ti 可以通过两种方式获得 INSTALL_PAKAGES 权限：使用固件密钥签署应用程序或将应用程序放入固件中。我的应用程序是从 /system/app 运行的，因此它必须获得特权。
有人知道出了什么问题并给我一些提示吗？谢谢
编辑：
前进一步，后退两步
我为应用添加了新权限
<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
但是新的
