这里给出关键部分代码，其余和文章《android 选择图片(从手机照相机或手机图片)》类似

 private void doCrop() {
		final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>();
    	
    	Intent intent = new Intent("com.android.camera.action.CROP");
        intent.setType("image/*");
        
        List<ResolveInfo> list = getPackageManager().queryIntentActivities( intent, 0 );
        
        int size = list.size();
        
        if (size == 0) {	        
        	Toast.makeText(this, "Can not find image crop app", Toast.LENGTH_SHORT).show();
        	
            return;
        } else {
        	intent.setData(mImageCaptureUri);
            
            intent.putExtra("outputX", 200);
            intent.putExtra("outputY", 200);
            intent.putExtra("aspectX", 1);
            intent.putExtra("aspectY", 1);
            intent.putExtra("scale", true);
            intent.putExtra("return-data", true);
            
        	if (size == 1) {
        		Intent i 		= new Intent(intent);
	        	ResolveInfo res	= list.get(0);
	        	
	        	i.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
	        	
	        	startAct…………………………………………………………………………
