Android 7.1 root后静默安装实现

pm install -r apkPath

-l 锁定应用程序
-r 重新安装应用，且保留应用数据
-t 允许测试apk被安装
-i <INSTALLER_PACKAGE_NAME> 指定安装包的包名
-s 安装到sd卡
-f 安装到系统内置存储中（默认安装位置）
-d 允许降级安装（同一应用低级换高级）
-g 授予应用程序清单中列出的所有权限（只有6.0系统可用）

使用-r安装时会有下面的异常，缺少 INTERACT_ACROSS_USERS_FULL权限，

添加 android:sharedUserId="android.uid.system" 

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

使用如下命令安装：
pm install -i 包名 --user 0 安装包路径

安装后自动启动需要监听安装完成广播：

    <receiver android:name=".receiver.UpdateReceiver">
        <intent-filter>
            <action android:name="android.intent.action.PACKAGE_REPLACED" />
            <action android:name="android.intent.action.PACKAGE_ADDED" />
            <action android:name="android.intent.action.PACKAGE_CHANGED" />
            <action android:name="android.intent.action.PACKAGE_REPLACED" />
            <action android:name="android.intent.action.PACKAGE_REMOVED" />

            <data android:scheme="package" />
        </intent-filter>
    </receiver>

public class UpdateReceiver extends BroadcastReceiver {

    public static final String APK_FILE_PATH = Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + Constants.UGO_APK;

    @Override
    public void onReceive(Context context, Intent intent) {
        if (Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction())) {
            Logger.i("install" + "安装了完成:" + "包名的程序");
            File file = new File(APK_FILE_PATH);
            if (file.exists() && file.isFile()) {
                Logger.i("install" + "删除了文件:" + APK_FILE_PATH);
                file.delete();
            } else {
                Logger.i("install" + "文件不存在:" + APK_FILE_PATH);
            }
            SPUtils.getInstance(context).saveData(HAS_UPDATE, HAS_UPDATE);
            Intent intent1 = context.getPackageManager().getLaunchIntentForPackage("包名");
            context.startActivity(intent1);
        }
        //接收安装广播
        if (Intent.ACTION_PACKAGE_ADDED.equals(intent.getAction())) {
            String packageName = intent.getDataString();
            Logger.e("install" + "安装了:" + packageName + "包名的程序");

        }

        }
    }
