Android中的摄像机意图和优先级队列
我目前正在编写一个Android应用程序（API级别2.3.3），它涉及从通过照相机意图拍摄的照片中获取300个最高灰度值。 接下来，函数（主要是数学和一些基于日历/时钟的）对结果值执行。 我正在使用Eclipse /模拟摄像头。
相机将启动并且照片拍摄没有问题，当我尝试保存照片（以及像素排序和数学/日历功能发生时）时，应用程序会崩溃。
我用相机意图和主变量（Y）的“虚拟”值测试了应用程序，并且这很好地工作。
出了什么问题？
以下是相关的代码部分：
int[] pixels;
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String _path = Environment.getExternalStorageDirectory() + File.separator + "sunpic.jpg";
File file = new File(_path);
Uri outputFileUri = Uri.fromFile(file);
Intent intent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, 1);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode) {
case (1): {
if (resultCode == RESULT_OK) {
Uri outputFileUri = data.getData();
try {
Bitmap bmp = android.provider.MediaStore.Images.Media.getBitmap(this.getContentResolver(), outputFileUri);
bmp.getPixels(pixels, 0, bmp.getWidth(), 0, 0, bmp.getWidth(), bmp.getHeight());
for(int x = 0; x < bmp.getWidth(); ++x) {
for(int y = 0; y < bmp.getHeight(); ++y) {
int index = y * bmp.getWidth() + x;
int R = (pixels[index] >> 16) & 0xff;
int G = (pixels[index] >> 8) & 0xff;
int B = pixels[index] & 0xff;
Double Grey = (0.299 * R + 0.587 * G + 0.114 * B);
int topSize = 300;
// priority queue to save the largest topSize values
PriorityQueue<Double> pq;
pq = new PriorityQueue<Double>(topSize+1);
double nv = Grey.floatValue();
if (pq.size() < topSize || pq.peek() < nv) {
// remove the smallest value from the queue only if it is full
if (pq.size() == topSize) {
pq.poll();
}
pq.add(nv);
}
double sum = 0;
for(Double d : pq) {
sum += d;
}
double Y = sum / 300;
在XML Manifest中，我有：
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-feature android:name="android.hardware.camera"/>

仍然没有运气，我已经改变了照相机意图代码：
@Override
public void onClick(View v) {
String _path = Environment.getExternalStorageDirectory().getAbsolutePath() + "sunpic.jpg";
File file = new File(_path);
//Uri fileUri = Uri.fromFile(file);
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, file);
//File file = new File(Environment.getExternalStorageDirectory().getPath());
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//super.onActivityResult(requestCode, resultCode, data);
if(requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE && resultCode == RESULT_OK) {
//Uri file = data.getData();
FileInputStream is;
try {
is = new FileInputStream("mnt/sdcard/sunpic.jpg");
Bitmap bmp = BitmapFactory.decodeStream(is);
//Bitmap bmp = android.provider.MediaStore.Images.Media.getBitmap(this.getContentResolver(), file);
//Bitmap bmp = (Bitmap) data.getExtras().get("data");
bmp.getPixels(pixels, 0, bmp.getWidth(), 0, 0, bmp.getWidth(), bmp.getHeight());
其余部分与我原来发布的内容完全相同。
logcat是空的，只要我在相机上拍照，它就会冻结。
我之前尝试的不包括
FileInputStream is;
try {
is = new FileInputStream("mnt/sdcard/sunpic.jpg");
并有下一行
Bitmap bmp = BitmapFactory.decodeStream("sunpic.jpg");
但是，这始终吐出NullPointer错误，我真的不明白为什么，尽管阅读了许多其他线程/其他网络资源。
