尝试从图库上传照片时崩溃。 并非所有图像都会导致崩溃，但很少有其他照片可以通过相机和图库成功上传。但无法理解为什么有些图像会导致崩溃。

无法理解为什么很少有图像会导致崩溃。 请帮忙。
答案 0 :(得分：0)
这是因为options.outHeight和options.outWidth返回0
试试这个
将Bitmap bmp = BitmapFactory.decodeFile(filePath, options);更改为
try {
InputStream in = getContentResolver().openInputStream(
Uri.parse(path));
bmp=BitmapFactory.decodeStream(in, null, options);
} catch (FileNotFoundException e) {
e.printStackTrace();
}

尝试获得这样的路径：
@TargetApi(Build.VERSION_CODES.KITKAT)
public String getPath(final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
if (isKitKat && DocumentsContract.isDocumentUri(activity, uri)) {
//Whether the Uri authority is ExternalStorageProvider.
if (com.android.externalstorage.documents".equals(uri.getAuthority()) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
}
}
// DownloadsProvider
else if ("com.android.providers.downloads.documents".equals(uri.getAuthority())) {
final String id = DocumentsContract.getDocumentId(uri);
final Uri contentUri = ContentUris.withAppendedId(
Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
return getDataColumn(activity, contentUri, null, null);
}
// MediaProvider
else if ("com.android.providers.media.documents".equals(uri.getAuthority())) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
Uri contentUri = null;
if ("image".equals(type)) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
} else if ("video".equals(type)) {
contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
} else if ("audio".equals(type)) {
contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
}
final String selection = "_id=?";
final String[] selectionArgs = new String[]{
split[1]
};
return getDataColumn(activity, contentUri, selection, selectionArgs);
}
else if ("content".equalsIgnoreCase(uri.getScheme())) {
//Goole photos uri
if ("com.google.android.apps.photos.content".equals(uri.getAuthority())
return uri.getLastPathSegment();
//Goole doc uri
else if ("com.google.android.apps.docs.storage".equals(uri.getAuthority()))
return uri.getLastPathSegment();
return getRealPathFromURI(uri);
} else if ("file".equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
}
return null;
}
getDataColumn是：
private String getDataColumn(Context context, Uri uri, String selection,
String[] selectionArgs) {
Cursor cursor = null;
final String column = "_data";
final String[] projection = {
column
};
try {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs,
null);
if (cursor != null && cursor.moveToFirst()) {
final int column_index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(column_index);
} else {
return uri.getPath();
}
} finally {
if (cursor != null)
cursor.close();
}
}
getRealPathFromURI是：
public String getRealPathFromURI(Uri contentURI) {
String result;
Cursor cursor = activity.getContentResolver().query(contentURI, null,
null, null, null);
if (cursor == null) {
result = contentURI.getPath();
} else {
cursor.moveToFirst();
try {
int idx = cursor
.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
result = cursor.getString(idx);
} catch (Exception e) {
AndyUtils
.showToast(
activity.getString(R.string.text_image_select_fail),
activity);
result = "";
}
cursor.close();
}
return result;
}

在日志文件中明确提到“权限被拒绝”，在清单文件中声明权限，然后重试。希望这能解决您的问题。
