【问题描述】：
在 Android 7.1 中从相机获取图像时将结果 ResultInfo{who=null, request=3, result=-1, data=null} 传递给 Activity 失败
我正在尝试从我的相机意图中获取和成像，但在尝试从我的 Uri 获取路径时遇到了错误，因为我需要将文件上传到我的服务器的路径。
这是我的代码
public String getRealPathFromURI(Uri uri) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
return cursor.getString(idx);
}
public String getPath(Uri uri) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
String document_id = cursor.getString(0);
document_id = document_id.substring(document_id.lastIndexOf(":") + 1);
cursor.close();
cursor = getContentResolver().query(
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null);
cursor.moveToFirst();
path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
cursor.close();
}
return path;
}
public void startCamera() {
Intent callCameraApplicationIntent = new Intent();
callCameraApplicationIntent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException e) {
e.printStackTrace();
}
String authorities = getApplicationContext().getPackageName() + ".provider";
currentImageUri = FileProvider.getUriForFile(this, authorities, photoFile);
callCameraApplicationIntent.putExtra(MediaStore.EXTRA_OUTPUT, currentImageUri);
callCameraApplicationIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
callCameraApplicationIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
startActivityForResult(callCameraApplicationIntent, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GALLERY_PICTURE && resultCode == RESULT_OK && data != null && data.getData() != null) {
try {
filePath = data.getData();
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd-MM-yyyy-hh-mm-ss");
String format = simpleDateFormat.format(new Date());
storedImagePath = tempFileImage(this, bitmap, "name" + format);
uploadMultipart();
} catch (IOException e) {
e.printStackTrace();
}
} else if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
filePath = currentImageUri;
uploadMultipart();
}
}
最后加载到服务器
public void uploadMultipart() {
//getting name for the image
String path = "";
String name = messageET.getText().toString().trim();
//getting the actual path of the image
if (currentImageUri != null) {
// path = getPath(currentImageUri);
path = getRealPathFromURI(currentImageUri);
}
if (filePath != null) {
path = getPath(filePath);
}
try {
String uploadId = UUID.randomUUID().toString();
String uploadUrl = "https://app.aer.media/v2/message_router/_sendMessage";
//Creating a multi part request
new MultipartUploadRequest(this, uploadId, uploadUrl)
.addFileToUpload(path, "mediaFile") //Adding file
.addParameter("data[message]", name) //Adding text parameter to the request
.addParameter("data[user_data]", k) //Adding text parameter to the request
// .setNotificationConfig(new UploadNotificationConfig())
.setMaxRetries(2)
.startUpload(); //Starting the upload
// getConvoData(k, "", "", false);
// rv_convo.getAdapter().notifyItemInserted(convobeans.size() - 1);
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), filePath);
ConvoResponseModel.DataBean.ConversationBean.MediaFileBean mf = new ConvoResponseModel.DataBean.ConversationBean.MediaFileBean();
mf.setImage(null);
mf.setThumb(null);
mf.setBitmap(bitmap);
long time = new Date().getTime() / 1000;
ConvoResponseModel.DataBean.ConversationBean conversationBean = new ConvoResponseModel.DataBean.ConversationBean();
conversationBean.setMessage("");
conversationBean.setIs_me(1);
conversationBean.setTime(String.valueOf(time));
conversationBean.setMediaFile(mf);
adapter.addItem(conversationBean);
// adapter.notifyItemInserted(convobeans.size - 1);
} catch (Exception exc) {
}
}
我可以在完全相同的路径上查看从我的文件管理中保存的图像，但是当我尝试将图像上传到服务器并调用它的 getpath() 时，它会引发错误
