Creating Folder In Internal Memory

I am unable to get the methods for creating folder in Internal Memory, i gone through few conversations in Android create folders in Internal Memory and Problem facing in reading

Solution 1:

try the below

Filemydir= context.getDir("users", Context.MODE_PRIVATE); //Creating an internal dir;if (!mydir.exists())
{
     mydir.mkdirs();
}     

Solution 2:

Here is the code which I am using for creating files in internal memory :

FilemyDir= context.getFilesDir();
    // Documents PathStringdocuments="documents/data";
    FiledocumentsFolder=newFile(myDir, documents);
    documentsFolder.mkdirs(); // this line creates data folder at documents directoryStringpublicC="documents/public/api." + server;
    FilepublicFolder=newFile(myDir, publicC);
    publicFolder.mkdirs(); // and this line creates public/api.myservername folder in internal memory

Solution 3:

To create directory on phone primary storage memory (generally internal memory) you should use following code. Please note that ExternalStorage in Environment.getExternalStorageDirectory() does not necessarily refers to sdcard, it returns phone primary storage memory

FilemediaStorageDir=newFile(Environment.getExternalStorageDirectory(), "MyDirName");

if (!mediaStorageDir.exists()) {
    if (!mediaStorageDir.mkdirs()) {
        Log.d("App", "failed to create directory");
        returnnull;
    }
}

Directory created using this code will be visible to phone user. The other method (as in accepted answer) creates directory in location (/data/data/package.name/app_MyDirName), hence normal phone user will not be able to access it easily and so you should not use it to store video/photo etc.

You will need permissions, in AndroidManifest.xml

<uses-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permissionandroid:name="android.permission.WRITE_INTERNAL_STORAGE" />

Solution 4:

<uses-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permissionandroid:name="android.permission.READ_EXTERNAL_STORAGE" />

Filedirect=newFile(Environment.getExternalStorageDirectory()+"/folder_name");

if(!direct.exists()) {
     if(direct.mkdir()); //directory is created;
}

Solution 5:

There is a "cacheDirectory" in your "data/package_name" directory.

If you want to store something in that cache memory,

FilecacheDir=newFile(this.getCacheDir(), "temp");
if (!cacheDir.exists())
    cacheDir.mkdir();

where this is context.
