我想通过从文件管理器中选择文件将文件上传到服务器，所以我使用以下代码通过单击按钮打开文件管理器：
button_upload_attachment.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String[] galleryPermissions = {android.Manifest.permission.READ_EXTERNAL_STORAGE, android.Manifest.permission.WRITE_EXTERNAL_STORAGE};
if (EasyPermissions.hasPermissions(CIBILCaptureandUPLOAD.this, galleryPermissions)) {
Intent intent = new Intent();
intent.setType("*/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, 1);
} else {
EasyPermissions.requestPermissions(this, "Access for storage",
101, galleryPermissions);
}
}
});
在 onActivityResult 方法中，我做了类似这样的事情来获取文件路径，并创建了一个 UploadToserver 函数用于上传。
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
//ImagesData = data;
try {
// When an Image is picked
if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK
&& null != data) {
Uri contentUri=data.getData();
Log.e("bbbbbbbbbbbbbb", contentUri.toString());
if(contentUri.toString().endsWith(".png")||contentUri.toString().endsWith("jpg") ||
contentUri.toString().endsWith(".pdf")){
photoFile= new File(contentUri.getPath());
if (photoFile.exists()) {
Log.e("photoFile", "File Exists");
}
if (photoFile != null) {
new AsyncTask<String, String, File>() {
ProgressDialog pd;
@Override
protected void onPreExecute() {
pd = ProgressDialog.show(CIBILCaptureandUPLOAD.this, "", "Compressing...");
Log.e("PreExecute", "Compressing");
}
@Override
protected File doInBackground(String[] params) {
return photoFile;
}
@Override
protected void onPostExecute(File result) {
pd.dismiss();
if (result != null) {
new CIBILCaptureandUPLOAD.UploadFileToServer().execute(result);
}
}
}.execute("");
}
}else {
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(contentUri,
filePathColumn, null, null, null);
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = "";
if (cursor.moveToFirst()) {
filePath = cursor.getString(columnIndex);
}
Log.e("PATH", filePath);
photoFile = new File(filePath);
if (photoFile.exists()) {
Log.e("photoFile", "File Exists");
}
if (photoFile != null) {
new AsyncTask<String, String, File>() {
ProgressDialog pd;
@Override
protected void onPreExecute() {
pd = ProgressDialog.show(CIBILCaptureandUPLOAD.this, "", "Compressing...");
Log.e("PreExecute", "Compressing");
}
@Override
protected File doInBackground(String[] params) {
return photoFile;
}
@Override
protected void onPostExecute(File result) {
pd.dismiss();
if (result != null) {
new CIBILCaptureandUPLOAD.UploadFileToServer().execute(result);
}
}
}.execute("");
}
}
}
在其他设备上它运行良好，但在三星设备上出现问题。
java.io.FileNotFoundException: /document/primary:Xender/other/When Strangers Meet_ 3 in 1 Box - John Harker.pdf: open failed: ENOENT (No such file or directory)
我的上传代码是
private class UploadFileToServer extends AsyncTask { private static final String TAG = "UploadFileToServer";
// private ProgressBar progressBar;
// private String filePath = null;
// private TextView txtPercentage;
private ProgressDialog pd;
long totalSize = 0;
@Override
protected void onPreExecute() {
// setting progress bar to zero
// progressBar.setProgress(0);
pd = ProgressDialog.show(CIBILCaptureandUPLOAD.this, "", "Loading...");
super.onPreExecute();
}
@Override
protected void onProgressUpdate(Integer... progress) {
// Making progress bar visible
// progressBar.setVisibility(View.VISIBLE);
// updating progress bar value
pd.setMessage("Loading..." + progress[0]);
// progressBar.setProgress(progress[0]);
// updating percentage value
// txtPercentage.setText(String.valueOf(progress[0]) + "%");
