I want to create a folder and put all generated file in this folder so I have created this method to create a directory in external storage named MyAppFolder and put a .nomedia file in this folder to avoid media indexing
static String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
static String baseAppDir = "MyAppFolder";
static String fileHider = ".nomedia";
public static void createFolder() {
try {
File mainDirectory = new File(baseDir + File.separator + baseAppDir);
if (!(mainDirectory.exists())) {
mainDirectory.mkdirs();
File outputFile = new File(mainDirectory, fileHider);
try {
FileOutputStream fos = new FileOutputStream(outputFile);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
} catch (Exception exc) {
System.out.println("ERROR: " + exc.toString());
exc.printStackTrace();
}
}
I'm testing this on emulator but doesn't work, and I cannot understand how should I fix it.
The error log is:
java.io.FileNotFoundException: /storage/sdcard/MyAppFolder/.nomedia: open failed: ENOENT (No such file or directory)
02-12 20:11:51.758 4899-4899/com.myapp.testapp W/System.err﹕ at libcore.io.IoBridge.open(IoBridge.java:409)

I have also tried with
File outputFile = new File(mainDirectory, fileHider);
if(!outputFile.exists()) {
outputFile.createNewFile();
}
try {
FileOutputStream fos = new FileOutputStream(outputFile, false);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
same result
Make sure you have the permission
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
Your code can work on my device. If you do have the permission, due to some tiny differences between our Android systems, you can try to create a hidden directory, and create a file inside of it.
static String baseAppDir = ".MyAppFolder";
static String fileHider = "nomedia";
Type in "ls -a" to check whether the hidden file has been really created. Don't 100% trust the exception log sometimes.
