我带回了从摄像头的意图回父意图的相机拍摄的图像(如一个byte [使用putExtra])时,你得到的logcat中的失败粘合剂事务错误。我不明白为什么,它不喜欢它的一个大的位图或任何东西。它只是发生在我拍照光线充足,因为这时的byte []越大。离开摄像机的意图时出现的错误。有没有人看到我的code错了吗?
下面是相机意图code:

这里是code调用摄像头意图:
意向意图=新的意图(Example.this,TakePicture.class);
intent.putExtra(layoutWidth,layoutWidth);
intent.putExtra(layoutHeight,layoutHeight);
startActivityForResult(意向,0);
解决方案
由于某些原因,Android不,当您尝试通过原始byte []数组或者从它创建了一个位图喜欢。有些人已经成功COM pressing生成位图,并通过它通过意向。我会建议先保存图像文件和发送它通过意向的路径。
I get the Failed binder transaction error in the logcat when returning the image taken with the camera from the camera intent back to the parent intent (as a byte[] using putExtra). I don't understand why, its not like its a big bitmap or anything. It only happens when i take pictures with lots of light, because then the byte[] is bigger. The error occurs when leaving the camera intent. Does anyone see a mistake in my code?
Here is the code of the camera intent:
package example.imaging.ape;
import java.io.IOException;
import java.util.Iterator;
import java.util.Set;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.PixelFormat;
import android.hardware.Camera;
import android.hardware.Camera.AutoFocusCallback;
import android.os.Bundle;
import android.util.Log;
import android.view.MotionEvent;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.view.View.OnTouchListener;
public class TakePicture extends Activity implements SurfaceHolder.Callback{
Camera mCamera;
Boolean mPreviewRunning = false;
int imageLayoutHeight;
int imageLayoutWidth;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setup camera surface
getWindow().setFormat(PixelFormat.TRANSLUCENT);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.cameralayout);
SurfaceView mSurfaceView = (SurfaceView) findViewById(R.id.hist_surface_camera);
SurfaceHolder mSurfaceHolder = mSurfaceView.getHolder();
mSurfaceHolder.addCallback(this);
mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
Bundle extras = getIntent().getExtras();
imageLayoutHeight = extras.getInt("layoutHeight");
imageLayoutWidth = extras.getInt("layoutWidth");
OnTouchListener touchListener = new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent e) {
System.out.println("MAKING PICTURE");
mCamera.autoFocus(cb);
return false;
}
};
//setup touch listener
mSurfaceView.setOnTouchListener(touchListener);
}
AutoFocusCallback cb = new AutoFocusCallback() {
public void onAutoFocus(boolean success, Camera c) {
c.takePicture(null, null, mPictureCallback);
}
};
Camera.PictureCallback mPictureCallback = new Camera.PictureCallback() {
public void onPictureTaken(byte[] imageData, Camera c) {
System.out.println("Picture taken, now returning");
Intent resultIntent = new Intent();
resultIntent.putExtra("cameraImage", imageData);
System.out.println("put Extra");
setResult(Activity.RESULT_OK, resultIntent);
finish();
}
};
//initialize camera
public void surfaceCreated(SurfaceHolder holder) {
mCamera = Camera.open();
}
public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
if (mPreviewRunning) {
mCamera.stopPreview();
}
Camera.Parameters p = mCamera.getParameters();
p.setPreviewSize(h, w);
System.out.println("PreviewSize: " + h + "," + w);
p.setPictureSize(h*3,w*3); // is around 1200x900
p.set("rotation", 90);
mCamera.setParameters(p);
try {
mCamera.setPreviewDisplay(holder);
} catch (IOException e) {
e.printStackTrace();
}
mCamera.startPreview();
mPreviewRunning = true;
}
public void surfaceDestroyed(SurfaceHolder holder) {
mCamera.stopPreview();
mPreviewRunning = false;
mCamera.release();
}
}
And here is the code that calls the camera intent:
Intent intent = new Intent(Example.this, TakePicture.class);
intent.putExtra("layoutWidth",layoutWidth);
intent.putExtra("layoutHeight",layoutHeight);
startActivityForResult(intent,0);
解决方案
For some reason, Android doesn't like when you try to pass the raw byte[] array or a Bitmap created from it. Some people have had success compressing the resulting Bitmap and passing that via Intent. I would recommend saving the image to a file first and sending it's path via the Intent.
