重新启动设备后，我的储物柜应用程序无法在Android棉花糖设备上工作

Question

我正在开发应用程序更衣室应用程序。如果在kitkat版本设备应用程序锁定中安装了这个 应用程序，并且它的 工作正常。在棉花糖|（6.0）版本设备最初 应用程序正在工作，如果我们重新启动设备应用程序锁定不是 工作，锁定的应用程序打开时不询问任何密码。 如果我们只是进入应用程序（应用程序锁定应用程序），并退出应用程序其 工作完美。这次它要求密码。

public class StartupServiceReceiver extends BroadcastReceiver { 
@Override 
public void onReceive(Context context, Intent intent) { 
    if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){ 
     if (AppLockerPreference.getInstance(context).isAutoStart()){

你能帮我吗。

Answer 1

检查设备是否棉花糖和授予权限

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.MARSHMALLOW) { 
    // only for marshmallow and newer versions 
} 

Answer 2

以下的Android 6.0（棉花糖），其只需要提清单档案中的所有权限，而在棉花糖及以上版本的所有的权限被授予由用户，你需要显示弹出权限。 一样，如果你想使用下面的权限，然后做这样的编码：

public void checkForMarshmallowPermission() { 

    for (int i = 0; i < 3; i++) { 
     switch (i) { 
      case 0: 
       isPermissionGiven(Manifest.permission.ACCESS_COARSE_LOCATION, PERMISSION_LOCATION_COARSE); 
       break; 

      case 1: 
       isPermissionGiven(Manifest.permission.ACCESS_FINE_LOCATION, PERMISSION_LOCATION_FINE); 
       break; 

      case 2: 
       isPermissionGiven(Manifest.permission.READ_PHONE_STATE, PERMISSION_READ_PHONE_STATE); 
       break; 
     } 
    } 

} 


private boolean isPermissionGiven(String permissionName, int requestCode) { 
     LoggerUtility.e(TAG, "isPermissionGiven :-" + permissionName); 
     if (ContextCompat.checkSelfPermission(LoginActivity.this, 
       permissionName) 
       != PackageManager.PERMISSION_GRANTED) { 
      ActivityCompat.requestPermissions(YourActivity.this, 
        new String[]{permissionName}, 
        requestCode); 
      return false; 
     } 
     return true; 
    } 

而且覆盖在你的活动onRequestPermissionsResult方法：

@Override 
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { 
     LoggerUtility.e(TAG, "onRequestPermissionsResult :-" + requestCode); 
     switch (requestCode) { 
      case PERMISSION_LOCATION_FINE: 
       if (grantResults.length > 0 
         && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 

        // permission was granted, yay! Do the 
        // contacts-related task you need to do. 
        isPermissionGiven(Manifest.permission.READ_PHONE_STATE, PERMISSION_READ_PHONE_STATE); 

       } else { 
        // permission denied, boo! Disable the 
        // functionality that depends on this permission. 
       } 
       break; 

      case PERMISSION_LOCATION_COARSE: 
       if (grantResults.length > 0 
         && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 

        // permission was granted, yay! Do the 
        // contacts-related task you need to do. 
        isPermissionGiven(Manifest.permission.READ_PHONE_STATE, PERMISSION_READ_PHONE_STATE); 

       } else { 

        // permission denied, boo! Disable the 
        // functionality that depends on this permission. 
       } 
       break; 

      case PERMISSION_READ_PHONE_STATE: 
       if (grantResults.length > 0 
         && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 

        // permission was granted, yay! Do the 
        // contacts-related task you need to do. 


       } else { 

        // permission denied, boo! Disable the 
        // functionality that depends on this permission. 
       } 
       break; 
     } 
    }
