安卓飞行模式更改

Question

我有一个生根手机(5.0.1(
我想每40秒打开和关闭飞行模式

不工作

Settings.System.putInt(getContentResolver(),Settings.System.AIRPLANE_MODE_ON, 1);

然后我尝试了：

public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String r1 = run_cmd("adb shell settings put global airplane_mode_on 1");
String r3 = run_cmd("adb shell am broadcast -a android.intent.action.AIRPLANE_MODE");
Log.e("test1", r1);
Log.e("test3", r3);
}
private String run_cmd(String command) {
StringBuilder output = new StringBuilder();
java.lang.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).append("n");
}
} catch (Exception e) {
e.printStackTrace();
}
return output.toString();
}
}

飞行模式如何变化？

🧐看起来你的帖子主要是代码;请添加更多细节。

Answer 1

cmd 代码

public static final boolean execute(String cmd) {
try {
if (cmd != null && cmd.length() > 0) {
Process p = Runtime.getRuntime().exec("su");
DataOutputStream dos = new DataOutputStream(p.getOutputStream());
dos.writeBytes(cmd + "n");
dos.writeBytes("exitn");
dos.flush();
dos.close();
p.waitFor();
} else {
Log.e(TAG, "command is null or empty");
}
} catch (IOException ex) {
Log.e(TAG, "IOException");
ex.printStackTrace();
} catch (SecurityException ex) {
Log.e(TAG, "SecurityException");
ex.printStackTrace();
} catch (Exception ex) {
Log.e(TAG, "Generic Exception");
ex.printStackTrace();
}
return false;
}

主要

public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
int second = 50;
new CountDownTimer(second * 1000, second * 1000) {
public void onTick(long l) {
}
public void onFinish() {
RootPrivileges.execute("settings put global airplane_mode_on 1;" +
"am broadcast -a android.intent.action.AIRPLANE_MODE --ez state true;");
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
RootPrivileges.execute("settings put global airplane_mode_on 0;" +
"am broadcast -a android.intent.action.AIRPLANE_MODE --ez state false;");
start();
}
}.start();
}
}
