I am working on a project which contains a module to scan pdf, doc xls files from sd card and make list of them. I also want to make list of folders only.
As I am very new to android. Anyone have idea of achieving this.
Here is my code:
public class MediaScannerWrapper implements
MediaScannerConnection.MediaScannerConnectionClient {
private MediaScannerConnection mConnection;
private String mPath;
private String mMimeType;
// filePath - where to scan;
// mime type of media to scan i.e. "image/jpeg".
// use "*/*" for any media
public MediaScannerWrapper(Context ctx, String filePath, String mime){
mPath = filePath;
mMimeType = mime;
mConnection = new MediaScannerConnection(ctx, this);
}
// do the scanning
public void scan() {
mConnection.connect();
}
// start the scan when scanner is ready
public void onMediaScannerConnected() {
mConnection.scanFile(mPath, mMimeType);
Log.w("MediaScannerWrapper", "media file scanned: " + mPath);
}
public void onScanCompleted(String path, Uri uri) {
// when scan is completes, update media file tags
}
}
On devices that run Android 9 (API level 28) or lower, your app can access the app-specific files that belong to other apps, provided that your app has the appropriate storage permissions.
public void walkdir(File dir) {
String pdfPattern = ".pdf";
File[] listFile = dir.listFiles();
if (listFile != null) {
for (int i = 0; i < listFile.length; i++) {
if (listFile[i].isDirectory()) {
walkdir(listFile[i]);
} else {
if (listFile[i].getName().endsWith(pdfPattern)){
//Do what ever u want
}
}
}
} }
To search on the whole sdcard call this function usingwalkdir(Environment.getExternalStorageDirectory());
