Android: How To Remove Files From External Storage?

I am implementing an application which generates and create files in External storage. How can I remove that? Edit I added following code and still I am getting the same problem.

Solution 1:

Filefile=newFile(selectedFilePath);
booleandeleted= file.delete();

where selectedFilePath is the path of the file you want to delete - for example:

/sdcard/YourCustomDirectory/ExampleFile.mp3

Solution 2:

This is another way just pass your directory name to delete content of it

ex "/sdcard/abc/yourdata"

publicvoiddeleteFiles(String path) {      
    Filefile=newFile(path);

    if (file.exists()) {
        StringdeleteCmd="rm -r " + path;
        Runtimeruntime= Runtime.getRuntime();
        try {
            runtime.exec(deleteCmd);
        } catch (IOException e) {

        }
    }

}

Solution 3:

I think you forgot to put the write permission in your AndroidManifest.xml file, that's why delete() always return false.

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

Solution 4:

Try the following code to delete the automatically created files and when you don't know where it is stored:

publicvoidclearApplicationData() {
    File cache = getCacheDir();
    File appDir = newFile(cache.getParent());
    if (appDir.exists()) {
        String[] children = appDir.list();
        for (String s : children) {
            if (!s.equals("lib")) {
                deleteDir(newFile(appDir, s));
                Log.i("TAG",
                        "**************** File /data/data/APP_PACKAGE/" + s
                                + " DELETED *******************");
            }
        }
    }
}

publicstaticbooleandeleteDir(File dir) {
    if (dir != null && dir.isDirectory()) {
        String[] children = dir.list();
        for (int i = 0; i < children.length; i++) {
            boolean success = deleteDir(newFile(dir, children[i]));
            if (!success) {
                returnfalse;
            }
        }
    }

    return dir.delete();
}

Solution 5:

Its very simple:

File file = new File(YOUR_IMAGE_PATH).delete();
if(file.exists())
    file.delete();

Hope it will help you.
