我正在开发一个Android应用程序。我有2个活动，MainActivity调用一个使用我的CameraActivity的意图，如下所述。
public class CameraActivity extends ActionBarActivity {
private static final int REQUEST_IMAGE = 100;
private static final int REQUEST_VIDEO = 200;
private static final int SELECT_IMAGE = 300;
Button mCaptureButton;
Button mGalleryButton;
ImageView mImageView;
TextView mText;
File mDestination;
int mMediaType = 0;
Uri mAttachedImage = null;
String mCurrentPhotoPath;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_camera);
mCaptureButton = (Button)findViewById(R.id.capture);
mCaptureButton.setOnClickListener(mCameraListener);
mGalleryButton= (Button)findViewById(R.id.gallery);
mCaptureButton.setOnClickListener(mGalleryListener);
mGalleryButton= (Button)findViewById(R.id.send);
mCaptureButton.setOnClickListener(mSendListener);
mImageView = (ImageView)findViewById(R.id.image);
mText = (TextView)findViewById(R.id.file);
//Generar una codificación para el nombre
//mCurrentPhotoPath = this.getImageFileName();
//mDestination = new File( Environment.getExternalStorageDirectory(), mCurrentPhotoPath + ".jpg");
mDestination = new File( Environment.getExternalStorageDirectory(), "MyImage.jpg");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_camera, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
String getImageFileName()
{
String mTimeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String sImgFileName = "GPS_JPG_" + mTimeStamp;
return sImgFileName;
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//PAra imágenes
if(requestCode == REQUEST_IMAGE && resultCode == Activity.RESULT_OK && mMediaType == 0) {
//Process and display the image
try{
FileInputStream in = new FileInputStream(mDestination);
//BitmapFactory.Options mOptions = new BitmapFactory.Options();
//mOptions.inSampleSize = 1; //Para reducir el tamaño del archivo
//Bitmap userImage = BitmapFactory.decodeStream(in, null, mOptions);
Bitmap userImage = BitmapFactory.decodeStream(in);
mImageView.setImageBitmap(userImage);
}catch ( Exception e)
{
e.printStackTrace();
}
//Bitmap userImage = (Bitmap)data.getExtras().get("data");
//mImageView.setImageBitmap(userImage);
}
//Para Video
if(requestCode == REQUEST_VIDEO && resultCode == Activity.RESULT_OK && mMediaType == 1) {
try{
String mLocation = data.getData().toString();
mText.setText(mLocation);
}catch ( Exception e)
{
e.printStackTrace();
}
}
//Para la Galería
if(requestCode == SELECT_IMAGE && resultCode == Activity.RESULT_OK) {
try{
Uri mSelectedImageTmp = data.getData();
InputStream mImageStream = getContentResolver().openInputStream(mSelectedImageTmp);
Bitmap mSelectedImage = BitmapFactory.decodeStream(mImageStream);
mImageView.setImageBitmap(mSelectedImage);
}catch ( Exception e)
{
e.printStackTrace();
}
}
}
/**

*/
private View.OnClickListener mCameraListener = new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
//Agregar codigo para diferenciar Foto de Video
if( mMediaType == 0){
Intent mIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
mIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mDestination));
if (mIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(mIntent, REQUEST_IMAGE);
}
}
else
{
Intent mIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
//Add (optional) extra to save video to our file
mIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mDestination));
//Optional extra to set video quality
mIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0);
if (mIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(mIntent, REQUEST_VIDEO);
}
}
} catch (ActivityNotFoundException e) {
//Handle if no application exists
}
}
};
private View.OnClickListener mGalleryListener = new View.OnClickListener(){
@Override
public void onClick(View v) {
try{
//Intent mPhotoSelectIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
Intent mPhotoSelectIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
mPhotoSelectIntent.setType("image/*");
if( Build.VERSION.SDK_INT >= 18){
mPhotoSelectIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
}
startActivityForResult(mPhotoSelectIntent, SELECT_IMAGE);
}
catch(Exception ex)
{
}
}
};
/**

private View.OnClickListener mSendListener = new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
};
}
所以问题是我收到了以下消息，打开相机的意图似乎被暂停了。我是Android的新手，所以我做错了什么？
希望你能帮助我。
这是我的Logcat
