    <p>I'm trying to create a reset app functionality for my application and I'm trying to delete all files from internal storage including <code>files folder</code>, <code>databases folder</code>and <code>shared preferences</code>. The problem is that not everytime when I try to delete these folder they are deleted. Sometimes the function which I use to delete the files returns false. In that case my application cannot work properly. Here is what I'm using :</p> <pre><code> @SuppressWarnings("static-access") public void deleteAllData(){ String cache = this.getCacheDir().toString(); Log.e("","dbPath : "+cache); File ChFolder = new File(cache); boolean cachee = deleteDirectory(ChFolder); Log.e("","Database Folder Delete Success : "+cachee); String server = rpc.getCurrentServerName(this); int userId = rpc.getUserId(this); String userDbPath = "/data/data/"+this.getPackageName()+"/databases/"+Integer.toString(userId)+"_"+server; File userDbFile = new File(userDbPath); boolean userDbFileTF = userDbFile.delete(); Log.e("","user Database Folder : "+userDbFileTF); String sysDbPath = "/data/data/"+this.getPackageName()+"/databases/stampii_sys_tpl.sqlite"; File sysDbFile = new File(sysDbPath); boolean sysDbFileTF = sysDbFile.delete(); Log.e("","user Database Folder : "+sysDbFileTF); // Delete Databases Folder : String dbPath = "/data/data/"+this.getPackageName()+"/databases/"; Log.e("","dbPath : "+dbPath); File dbFolder = new File(dbPath); boolean dbFold = deleteDirectory(dbFolder); Log.e("","Database Folder Delete Success : "+dbFold); // Delete Files Folder : String name = this.getFilesDir().toString()+"/users/"; Log.e("","path : "+name); File files = new File(name); boolean filesFol = deleteDirectory(files); Log.e("","filesFol : "+filesFol); } static public boolean deleteDirectory(File path) { if( path.exists() ) { File[] files = path.listFiles(); if (files == null) { return true; } for(int i=0; i&lt;files.length; i++) { if(files[i].isDirectory()) { deleteDirectory(files[i]); } else { files[i].delete(); } } } return( path.delete() ); } </code></pre> <p>Is there something I'm missing and how can I implement function like <code>Clear Data</code> in Android Settings which will delete the databases too. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
