public class AndroidLogcatScannerThread extends Thread {    private LogcatObserver observer;    public AndroidLogcatScannerThread(LogcatObserver observer) {            this.observer = observer;    }    public void run() {            String[] cmds = { "logcat", "-c" };            String shellCmd = "logcat";            Process process = null;            InputStream is = null;            DataInputStream dis = null;            String line = "";            Runtime runtime = Runtime.getRuntime();            try {                    observer.handleLog(line);                    int waitValue;                    waitValue = runtime.exec(cmds).waitFor();                    observer.handleLog("waitValue=" + waitValue + "\n Has do Clear logcat cache.");                    process = runtime.exec(shellCmd);                    is = process.getInputStream();                    dis = new DataInputStream(is);                    while ((line = dis.readLine()) != null) {                    //Log.d("Log","Log.Bestpay:"+line);                                        if(observer!=null)                            observer.handleLog(line);                                                  }            } catch (InterruptedException e) {                    e.printStackTrace();            } catch (IOException ie) {                    ie.printStackTrace();            } finally {                    try {                            if (dis != null) {                                    dis.close();                            }                            if (is != null) {                                    is.close();                            }                            if (process != null) {                                    process.destroy();                            }                    } catch (Exception e) {                            e.printStackTrace();                    }            }    }}

上面的代碼基本實現了卸載提示，最後不要忘了許可權：

 

 

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