重新启动设备后，我的储物柜应用程序无法在 Android 棉花糖设备上运行

Question

我正在开发应用储物柜应用程序。如果安装了这个 kitkat版设备应用程序锁定及其应用 工作完美。在 marshmallow|(6.0) 版本设备中最初 应用程序正在运行，如果我们重新启动设备应用程序锁不 工作时，锁定的应用程序无需询问任何密码即可打开。 如果我们只是进入应用程序（应用程序锁定应用程序）并从应用程序退出 工作完美。那个时候它会询问密码。

public class StartupServiceReceiver extends BroadcastReceiver {
@Override

    if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){

你能帮帮我吗？

Answer 1

检查设备是否是棉花糖并授予权限

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

Answer 2

在 Android 6.0 (MARSHMALLOW) 以下只需要在清单文件中提及所有权限，而在棉花糖及以上版本中，所有权限均由用户授予，因此您需要显示权限弹出窗口。 就像如果你想使用以下权限，然后像这样进行编码：

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;
    }

同时在你的活动中重写 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;
        }
    }
