Как я могу запустить SERVICE в android

Question

Я разрабатываю блокировку приложения в android. Я пытаюсь использовать службу, чтобы мое приложение работало в фоновом режиме, но, похоже, оно не запускается. Я также хотел бы реализовать экран пароля для выбранных приложений, которые пользователь хочет заблокировать. Я закодированы некоторые из них:

MainActivity.java

public class MainActivity extends Activity implements OnClickListener { 
    private ListView list; 
    ArrayList<Model> data; 
    ApkAdapter adapter; 
    private PackageManager packageManager; 
    TextView tView; 
    ProtectAppProvider pap; 
    CheckBox chk; 
    ArrayList<String> protectedApps; 
    List<PackageInfo> appsList; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     packageManager = getPackageManager(); 
     tView = (TextView) findViewById(R.id.appname); 
     list = (ListView) findViewById(R.id.applist); 
     appsList = getPackageManager().getInstalledPackages(0); 
     data = new ArrayList<Model>(); 

     initialization(); 
     getApps(); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     MenuInflater inflater = getMenuInflater(); 
     inflater.inflate(R.menu.main_activity_bar, menu); 
     return super.onCreateOptionsMenu(menu); 
    } 

    @Override 
    public void onClick(View view) { 
     boolean isChecked; 
     boolean diditwork = true; 
     int getPosition = (Integer) view.getTag(); 
     Model obj = data.get(getPosition); 
     String aName = obj.getAppName(); 
     String pName = obj.getpName(); 
     protectedApps = new ArrayList<String>(); 
     pap = new ProtectAppProvider(getApplicationContext()); 
     if (((CheckBox) view).isChecked()) { 
      try { 
       isChecked = true; 
       data.get(getPosition).setSelected(isChecked); 
       protectedApps.add(aName); 
       pap.open(); 
       pap.createEntry(aName,pName); 
       pap.close(); 
      } catch (Exception e) {

      } finally { 
       if (diditwork)

       else 
        Toast.makeText(this, "Fail to lock!", Toast.LENGTH_SHORT).show(); 

      } 

     } else {

      data.get(getPosition).setSelected(isChecked); 
      diditwork = true; 
      try { 
       pap.open(); 
       protectedApps.remove(aName); 
       pap.deleteEntry(aName); 
       pap.close(); 
      } catch (Exception e) { 
       diditwork = false; 
      } finally {

     } 

    } 
    public void getApps(){ 
     for (int i = 0; i < appsList.size(); i++) { 
      PackageInfo p = appsList.get(i); 
      if (packageManager.getLaunchIntentForPackage(p.packageName) != null 
        && ((!p.applicationInfo.loadLabel(getPackageManager()) 
          .toString().equals("VoiceAppLock")))) { 
       Model model = new Model(); 
       model.setAppName(p.applicationInfo.loadLabel(
         getPackageManager()).toString()); 
       model.setAppIcon(p.applicationInfo 
         .loadIcon((getPackageManager()))); 
       model.setpName(p.packageName); 
       data.add(model); 

       Collections.sort(data, Model.AppComparator); 

      } 
     } 
     adapter = new ApkAdapter(MainActivity.this, data, packageManager, 
       protectedApps);

Answer 1

В вашем BootStartReceiver классе, попробуйте следующее:

public class BootStartReceiver extends BroadcastReceiver { 
    @Override 
    public void onReceive(Context context, Intent intent) { 
     if (intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED)) { 
      // Start sensor service. 
      intent = new Intent(context, LockServices.class); 
      context.startService(intent); 
     } 
    } 
} 

Вам также может понадобиться объявить BootStartReceiver в файле AndroidManifest.xml следующим образом:

<receiver 
    android:name=".BootStartReceiver" 
    android:enabled="true" 
    android:exported="false"> 
    <intent-filter> 
     <action android:name="android.intent.action.BOOT_COMPLETED"/> 
    </intent-filter> 
</receiver>
