我收到此错误:执行停止未恢复LoginActivity的活动.我已经阅读了有关此错误的其他主题,但我仍然无法看到问题所在.

这是我的Logcat:

我的活动:

public class LoginActivity extends Activity {
 EditText edtMail,edtPass;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);
    Button regButton = (Button) findViewById(R.id.registerbtn);
    Button logButton = (Button) findViewById(R.id.login);

    final Context context = getApplicationContext();
    edtMail = (EditText) findViewById(R.id.email);
    edtPass = (EditText) findViewById(R.id.pword);
    // testing …

我正在尝试使用getActionBar(); 方法,我收到此错误:需要android.support.v7.app.ActionBar找到android.app.ActionBar.我怎么能纠正这个？

我不知道如何在 Android 中获取位置（拍照时的 GPS/网络）。欢迎任何建议和代码示例。我直到现在还没有使用定位服务，我尝试了很多方法，但我无法让它工作。

这是我的图像捕获活动：

public class ImageCaptureActivity extends Activity {

// Activity request codes
private static final int CAMERA_CAPTURE_IMAGE_REQUEST_CODE = 100;
public static final int MEDIA_TYPE_IMAGE = 1;
Context context = null;

// directory name to store captured images
private static final String IMAGE_DIRECTORY_NAME = "Asisoft";

private Uri fileUri; // file url to store image

private ImageView imgPreview;
private Button btnCapturePicture;

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

    context = getApplicationContext();
    imgPreview = (ImageView) findViewById(R.id.imgPreview);
    btnCapturePicture = (Button) …
