本文介绍了无法通过/system/app 的 INSTALL_PACKAGES 权限以编程方式安装应用程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图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
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
我的安装程序位于root手机上的/system/app，勾选安装非市场应用程序"，安装程序有权限
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"/>
这是我的调用函数
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

我已经读到 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.我的应用程序从/system/app 运行，因此它必须获得权限.
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.
有人知道出了什么问题并给我一些提示吗?谢谢
Some one know what is wrong and give me some hints? Thanks
我们为应用添加了新权限
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"/>
不再出错
Neither user 10057 nor current process has android.permission.INSTALL_PACKAGES
但是新的

让我的手机崩溃、冻结和重启
make my phone crash, freez and reboot
推荐答案
基本上，
- 添加所需的
- 将 apk 推送到/system/priv-app
完成(好吧，至少对我有用).
Done (well, at least works for me).
您不需要添加 android:protectionLevel="signatureOrSystem" 或 android:sharedUserId="android.uid.system".您可以使用任何证书签名.
You do not need to add android:protectionLevel="signatureOrSystem" or android:sharedUserId="android.uid.system". You could sign with any certification.
