我想捕获图像并将其保存在我的应用程序之一的图像视图中。我已经知道如何实现它，并且在除三星Galaxy S3之外的所有设备中都能正常工作。
我想要的是什么：避免三星Galaxy S3中的强制关闭问题以及可能尚未测试过的所有其他设备。
我做了什么：我已完成以下代码以实现我的目标。

我在很多SO链接中搜索过这个问题但是没有得到任何解决方案。请帮助我摆脱这个。
我想在这里做一个说明，我没有真正的设备来测试这个问题 但是我的客户在真实设备上遇到了这个问题。我已经制作了一个与S3相同的模拟器，并且在每种情况下都不用担心。我不知道为什么只在真实设备上发生这种情况。
先谢谢
已编辑：我已通过修改以下代码并作为答案解决了上述问题。你可以在阅读问题后看看。
答案 0 :(得分：9)
我已经花费了很多时间来解决这个问题，并且在下面修改代码的过程中让代码在大多数设备中工作：
任何人将来都有同样的问题可以试试下面的代码。
调用图像捕获意图时：
String storageState = Environment.getExternalStorageState();
if (storageState.equals(Environment.MEDIA_MOUNTED)) {
Intent intent = new Intent(
MediaStore.ACTION_IMAGE_CAPTURE);
String filename = System.currentTimeMillis() + ".jpg";
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, filename);
mImageCaptureUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
values);
intent.putExtra(
android.provider.MediaStore.EXTRA_OUTPUT,
mImageCaptureUri);
try {
startActivityForResult(intent, PICK_FROM_CAMERA);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
} else {
new AlertDialog.Builder(BuildInukshk_4_Camera.this)
.setMessage(
"External Storeage (SD Card) is required.\n\nCurrent state: "
+ storageState)
.setCancelable(true).create().show();
}
} else { // pick from file
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Complete action using"), PICK_FROM_FILE);
}
内部OnActivityResult方法：
case PICK_FROM_CAMERA:
Log.i("TAG", "Inside PICK_FROM_CAMERA");
// Final Code As Below
try {
Log.i("TAG", "inside Samsung Phones");
String[] projection = {
MediaStore.Images.Thumbnails._ID, // The columns we want
MediaStore.Images.Thumbnails.IMAGE_ID,
MediaStore.Images.Thumbnails.KIND,
MediaStore.Images.Thumbnails.DATA };
String selection = MediaStore.Images.Thumbnails.KIND + "=" + // Select
// only
// mini's
MediaStore.Images.Thumbnails.MINI_KIND;
String sort = MediaStore.Images.Thumbnails._ID + " DESC";
// At the moment, this is a bit of a hack, as I'm returning ALL
// images, and just taking the latest one. There is a better way
// to
// narrow this down I think with a WHERE clause which is
// currently
// the selection variable
Cursor myCursor = this.managedQuery(
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
projection, selection, null, sort);
long imageId = 0l;
long thumbnailImageId = 0l;
String thumbnailPath = "";
try {
myCursor.moveToFirst();
imageId = myCursor
.getLong(myCursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.IMAGE_ID));
thumbnailImageId = myCursor
.getLong(myCursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID));
thumbnailPath = myCursor
.getString(myCursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA));
} finally {
// myCursor.close();
}
// Create new Cursor to obtain the file Path for the large image
String[] largeFileProjection = {
MediaStore.Images.ImageColumns._ID,
MediaStore.Images.ImageColumns.DATA };
String largeFileSort = MediaStore.Images.ImageColumns._ID
+ " DESC";
myCursor = this.managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
largeFileProjection, null, null, largeFileSort);
String largeImagePath = "";
try {
myCursor.moveToFirst();
// This will actually give yo uthe file path location of the
// image.
largeImagePath = myCursor
.getString(myCursor
.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.DATA));
mImageCaptureUri_samsung = Uri.fromFile(new File(
largeImagePath));
mImageCaptureUri = null;
} finally {
// myCursor.close();
}
// These are the two URI's you'll be interested in. They give
// you a
// handle to the actual images
Uri uriLargeImage = Uri.withAppendedPath(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
String.valueOf(imageId));
Uri uriThumbnailImage = Uri.withAppendedPath(
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
String.valueOf(thumbnailImageId));
// I've left out the remaining code, as all I do is assign the
// URI's
// to my own objects anyways...
} catch (Exception e) {
mImageCaptureUri_samsung = null;
Log.i("TAG",
"inside catch Samsung Phones exception " + e.toString());
}
try {
Log.i("TAG",
"URI Samsung:" + mImageCaptureUri_samsung.getPath());
} catch (Exception e) {
Log.i("TAG", "Excfeption inside Samsung URI :" + e.toString());
}
try {
Log.i("TAG", "URI Normal:" + mImageCaptureUri.getPath());
} catch (Exception e) {
Log.i("TAG", "Excfeption inside Normal URI :" + e.toString());
}
break;
运行以下代码后，您将获得两个URI mImageCaptureUri_samsung和mImageCaptureUri
如果您使用简单设备运行应用程序，您将获得mImageCaptureUri作为路径，如果您使用的设备与三星Galaxy S3一起运行，您将获得mImageCaptureUri_samsung中的Cpatured Image路径。
此外，您可以继续执行您的准则。它对我来说非常好用我测试过的所有设备。
如果有人遇到上述代码问题，他们可以参考下面很棒的链接Solution of Samsung Galaxy S3
希望它会有所帮助。
