以編程方式使用命令使應用程序包成為設備所有者

Question

我一直在以設備所有者的身份制作軟件包，但未成功。 我已經將我的設備植根於相同的位置。 我正在使用此命令。

                val exe = ShellExecuter()
                var command = "dpm set-device-owner $packageName/ .MyDeviceAdminReceiver"
                val outp = exe.Executer(command)

ShellExecuter代碼段

public String Executer(String command) {
                    StringBuffer output = new StringBuffer();
                    Process p;
                    try {
                        p = Runtime.getRuntime().exec(command);
                        p.waitFor();
                        BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
                        String line = "";
                        while ((line = reader.readLine())!= null) {
                            output.append(line + "\n");
                        }
                    } catch (Exception e) {`enter code here`
                        e.printStackTrace();
                    }
                    String response = output.toString();
                    return response;
                } 

MyDeviceAdminReceiver片段

class MyDeviceAdminReceiver : DeviceAdminReceiver() {
    companion object {
        fun getComponentName(context: Context): ComponentName {
            return ComponentName(context.applicationContext, MyDeviceAdminReceiver::class.java)
        }

        private val TAG = MyDeviceAdminReceiver::class.java.simpleName
    }

    override fun onLockTaskModeEntering(context: Context?, intent: Intent?, pkg: String?) {
        super.onLockTaskModeEntering(context, intent, pkg)
        Log.d(TAG, "onLockTaskModeEntering")
    }

    override fun onLockTaskModeExiting(context: Context?, intent: Intent?) {
        super.onLockTaskModeExiting(context, intent)
        Log.d(TAG, "onLockTaskModeExiting")
    }
}

device_admin_reciever代碼段

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<device-admin>
    <uses-policies>
        <limit-password />
        <watch-login />
        <reset-password />
        <force-lock />
        <wipe-data />
        <expire-password />
        <encrypted-storage />
        <disable-camera />
    </uses-policies>
</device-admin>

我想以編程方式使用命令或任何其他建議的方式使我的植根設備所有者成為我的應用程序包的所有者。

Answer 1

如果您是設備的root用戶，則可以按照此方法成為設備所有者。

首先，創建具有以下內容的文件device_owner.xml：

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<device-owner package="your.owner.app.package.id" name="Your app name" />

現在執行以下步驟

adb push device_owner.xml /sdcard/

adb shell

su

cp /sdcard/device_owner.xml /data/system/

cd /data/system/

chown system:system device_owner.xml

reboot

注意：重新啟動設備之前，請確保已安裝要成為設備所有者的應用程序。 如果您不這樣做，則將無限期獲得啟動動畫。

檢查此問題如何使我的應用成為設備所有者？

Answer 2

創建xml文件，然后從您的代碼復制到正確的位置/data/system/device_owner.xml，然后執行此代碼以設置適當的權限。 並調用重新啟動命令

final String[] run_cmd = new String[]{"chown","system:system","/data/system/device_owner.xml"};
String reboot = "/system/bin/reboot";

execute(null,run_cmd);
execute(null,reboot);


 public void execute(Map<String, String> environvenmentVars, String[] cmd) {

            try {

                Process process = Runtime.getRuntime().exec(cmd);
                BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));

                StringBuffer output = new StringBuffer();

                char[] buffer = new char[4096];
                int read;

                while ((read = reader.read(buffer)) > 0) {
                    output.append(buffer, 0, read);
                }

                reader.close();

                process.waitFor();    
                BufferedReader reader2 = new BufferedReader(new InputStreamReader(process.getErrorStream()));    
                StringBuffer output2 = new StringBuffer();

                char[] buffer2 = new char[4096];
                int read2;

                while ((read2 = reader2.read(buffer2)) > 0) {
                    output2.append(buffer2, 0, read2);
                }

                reader.close();
                process.waitFor();
                }

            catch (Exception e)
            {

            }

        }
