IllegalArgumentException on MediaMetadataRetriever.setDataSource()

I am trying to get few frames from a video file. And getting java.lang.IllegalArgumentException in the setDataSource line below.
String root = Environment.getExternalStorageDirectory().getAbsolutePath()+"/";
String path=root + "master" + File.separator +"master.mp4";
Uri videoFileUri=Uri.parse(path);
File myFile = new File(path);
MediaMetadataRetriever retriever = new MediaMetadataRetriever();
retriever.setDataSource(myFile.getAbsolutePath()); //getting error here
ArrayList<Bitmap> rev=new ArrayList<Bitmap>();
//Create a new Media Player
MediaPlayer mp = MediaPlayer.create(getBaseContext(), videoFileUri);
int millis = mp.getDuration();
for(int i=0;i<millis;i+=100){
Bitmap bitmap=retriever.getFrameAtTime(i,OPTION_CLOSEST_SYNC);
rev.add(bitmap);}

Google sign-in fails on Android

I ask the user to sign in:
DeezerConnect deezerConnect = new DeezerConnect(this, APP_ID);
DialogListener listener = new DialogListener(){
#Override
void onComplete(Bundle values) {
SessionStore session = new SessionStore();
session.save(deezerConnect, MainActivity.this);
Toast.makeText(MainActivity.this, "Sign in successful", Toast.LENGTH_SHORT).show();
}
#Override
void onCancel() {
Toast.makeText(MainActivity.this, "Sign in required", Toast.LENGTH_SHORT).show();
}
#Override
void onException(Exception e) {
e.printStackTrace();
}
}
deezerConnect.authorize(this, PERMISSIONS, listener);
Normal and Facebook sign-in seem to be working fine, but when I tap the Sign in with Google button, the login dialog closes, and in Logcat I see the following lines:

File not found error for no apparent reason?

My application should save a piechart as a png on the external storage. However this error appears:
java.io.FileNotFoundException: /storage/emulated/0/SAVE IMAGE EXAMPLE/myimage.png (No such file or directory)
I followed the instructions to add this kind of functionality very closely (From this tutorial), but yet the error appears. The app has the permission to write to external storage, I added the permission in my android_manifest.xml.
Can you guys spot the error? Because i can not.
If you also can't find the error, can you recommend any other way to do this?
Im using MPAndroidChart, but i don't really think it has to do with this, because i could try to save any other object and the error remains.
The code is
final PieChart piechart = (PieChart) findViewById(R.id.piechart);
button2.setOnClickListener(new View.OnClickListener() {
public void onClick (View v) {
Toast.makeText(Main.this, "Chart Saved", Toast.LENGTH_SHORT).show();
piechart.setCenterText("Test");
Bitmap bitmap;
OutputStream output;
bitmap = BitmapFactory.decodeResource(getResources(),R.id.piechart);
File filepath = Environment.getExternalStorageDirectory();
File dir = new File(filepath.getAbsolutePath()+"/SAVE IMAGE EXAMPLE");
dir.mkdirs();
File file = new File(dir, "myimage.png");
try {
output = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, output);
output.flush();
output.close();
}catch(Exception e){
e.printStackTrace();
}
}
});

You need to implement Runtime Permission model to get Storage Permission from user from marshmallow and above.
See the example here for storage permission

java.io.FileNotFoundException: /sdcard/Hotel_Manager/HotelsMangerUser.dat (No such file or directory)

In my activity when the user login
I check if the file with the user list exists , in case the method returns false , I create a new file where to save this list.
This is the method:
public boolean isLoginFilePresent() {
file = new File(loginData.getPath());//file name /sdcard/Hotel_Manager/HotelsMangerUser.dat;
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
present = file.exists();
return present;
}
But I get the following error ( this is the log ):
java.io.FileNotFoundException: /sdcard/Hotel_Manager/HotelsMangerUser.dat (No such file or directory)

What I wrong?
Thanks for helping me!!!!

This is the method for save user into file
public void saveLoginData(Set<User> accountSet, Context context) {
final List<String> loginFile = new ArrayList<>();
for (final User u : accountSet) {
loginFile.add(u.getName() + Constants.USERDATA_SEPARATOR + u.getPassword() +
Constants.USERDATA_SEPARATOR + u.getAccessLevel().toString());
}
try {
sdDir = new File(Constants.USER_DIR); //USER_DIR = "/sdcard/Hotel_Manger"
sdDir.mkdirs();
userOutput = new File(sdDir,Constants.USER_PATH);//USER_PATH = "HotelManagerUser.dat"
fos = new FileOutputStream(userOutput); //<------this return FileNotFoundException e
out = new ObjectOutputStream(fos);
out.writeObject(loginFile);
out.close();
fos.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

File.createNewFile() method throws exception in Android M

I have a problem to create file in Android M.
I use Nexus 9 with Android 6.0.1. Then I set in my project as below:
AndroidManifest.xml
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
build.gradle
android {
defaultConfig {
targetSdkVersion 23
...
}
}
MainActivity.Java
public class MainActivity extends AppCompatActivity {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String storagePath = Environment.getExternalStorageDirectory().getAbsolutePath();
String rootPath = storagePath + "/test";
String fileName = "/test.zip";
File root = new File(rootPath);
if(!root.mkdirs()) {
Log.i("Test", "This path is already exist: " + root.getAbsolutePath());
}
File file = new File(rootPath + fileName);
try {
if (!file.createNewFile()) {
Log.i("Test", "This file is already exist: " + file.getAbsolutePath());
}
} catch (Exception e) {
e.printStackTrace();
}
}
Build was success and application was launched, but I got exception message like this:

How can I solve this problem? I don't catch what I miss....
Please help.

Updated
Replace storagePath to access scoped storage, for Android 10.
Refer this document for more detail.
Thanks, laalto.
I didn't know about runtime permission.
I solved exception like this:
MainActivity.java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
/* Request user permissions in runtime */
ActivityCompat.requestPermissions(MainActivity.this,
new String[] {
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE
},
100);
/* Request user permissions in runtime */
createTestFile();
}
#TargetApi(23)
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case 100:
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED
&& grantResults[1] == PackageManager.PERMISSION_GRANTED) {
// User checks permission.
} else {
Toast.makeText(MainActivity.this, "Permission is denied.", Toast.LENGTH_SHORT).show();
finish();
}
}
}
private void createTestFile() {
// String storagePath = Environment.getExternalStorageDirectory().getAbsolutePath();
// If Target API level is 29(Android 10),
// you should access local path in scoped storage mode.
File localStorage = getExternalFilesDir(null);
if (localStorage == null) { return; }
String storagePath = localStorage.getAbsolutePath();
String rootPath = storagePath + "/test";
String fileName = "/test.zip";
File root = new File(rootPath);
if(!root.mkdirs()) {
Log.i("Test", "This path is already exist: " + root.getAbsolutePath());
}
File file = new File(rootPath + fileName);
try {
int permissionCheck = ContextCompat.checkSelfPermission(
MainActivity.this,
android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
if (permissionCheck == PackageManager.PERMISSION_GRANTED) {
if (!file.createNewFile()) {
Log.i("Test", "This file is already exist: " + file.getAbsolutePath());
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
It works!

I was having the same problem. I got an IOException on the file.createNewFile. A closer look at the exception reveals that it was due to "permissions denied". I was writing to my getFilesDir, so I shouldn't need an in the android manifest to accomplish this task. I of course added both READ and WRITE permissions for external storage, and of course, that didn't fix the problem.
I had been testing the code using a NEXUS 6 emulator with sdk 26. Without changing any code, I tried testing using a PIXEL C emulator with sdk 26 and the problem did not occur. So there seems to be some problem with my Nexus 6 emulator.
I suspect that this hasn't always been a problem and that this emulator instance got corrupted, but I haven't verified that. I did take the time to look at the linux file permission on the directories I was creating the file into an it reported "drwxrwxrwx", which is correct. I will add that I've implemented a FileProvider with paths to the directory I'm trying to create the new file at. The code I'm using pretty much looks like the code that Kae10 shows.
I traced the problem down to this code in UnixFileSystem:
public boolean createFileExclusively(String path) throws IOException {
BlockGuard.getThreadPolicy().onWriteToDisk();
return createFileExclusively0(path);
}
the exception is thrown from createFileExlussively0, which I not able to debug into. I haven't investigated this issue any further (i.e. 1.) would deleting the avd instance and recreating it help, my guess is that might, 2.) is there a later system image I should be using?)
