android實現卸載提示

       這篇文章是整理的以前用過的一個功能，由於多種原因現在停用了，也希望這篇文章能協助一些android入門的小童鞋。android是不提供監控卸載自己的功能的，這裡使用了監控android日誌的功能，android日誌相關知識可以參考《adb logcat 查看日誌》這篇文章。

        android卸載提示的思路是啟動一個服務監控android系統的列印日誌，當監控到"android.intent.action.DELETE"並且包含自己應用的包名時，提示給使用者。

監控代碼

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();                    }            }    }}

監控服務：

public class AndroidLogcatScannerService extends Service implements LogcatObserver{@Overridepublic void onCreate() {// TODO Auto-generated method stubsuper.onCreate();}@Overridepublic void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();}@Overridepublic void onStart(Intent intent, int startId) {// TODO Auto-generated method stubsuper.onStart(intent, startId);AndroidLogcatScannerThread scannerThread=new AndroidLogcatScannerThread(AndroidLogcatScannerService.this);scannerThread.start();}@Overridepublic IBinder onBind(Intent intent) {// TODO Auto-generated method stubreturn null;}@Overridepublic void handleLog(String info) {// TODO Auto-generated method stubif (info.contains("android.intent.action.DELETE") && info.contains(getPackageName())) {            Intent intent = new Intent();            intent.setClass(AndroidLogcatScannerService.this, UninstallActivity.class);            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);            startActivity(intent);        }}}

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>
