I'm trying to displaying a device supported format programmatically. i have found this on the internet. the question is, how to display those ? please help me, im newbie in Android development.
Here is the code for checking file format of the device.

It is referenced in the android documentation here: https://developer.android.com/guide/topics/providers/content-provider-creating.html#MIMETypes
Note that these MIME types are supported only if the user has the appropriate app for it. I don't think that you can display the supported MIME types programmatically. However you can check if the one that you want to use is supported using code like this :
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(someUri, "YOUR_MIME_TYPE_HERE");
if(intent.resolveActivity(activity.getPackageManager()) != null)
{
lActivity.startActivity(intent);
}
else
{
Log.w(TAG, "There is no application for this MIME type");

Tell me why?
Try changing all the "http" 's to "https".
at first, i am using Nexus 7 as my testing device.
i want to save a class object with its all variables current value in a file and want to save the file in such place so that, after reboot of the phone (assuming that the phone is shutted down by the user) , i can get the object from the file and can use the data (which are saved in the variables in the saved object class) for my further use. where should i save my file (with the object) such that, it will work for most of the devices.
here is my code(writting a class object in a file in extarnal storage):
File file = new File(Environment.getExternalStorageDirectory(), "savedData");
if(!file.exists()){
file.createNewFile();
Toast.makeText(getActivity(), "not exist", Toast.LENGTH_LONG).show();
}else{
Toast.makeText(getActivity(), "exist", Toast.LENGTH_LONG).show();
}
if(file.canWrite())
Toast.makeText(getActivity(), "writable", Toast.LENGTH_LONG).show();
else
Toast.makeText(getActivity(), "not writable", Toast.LENGTH_LONG).show();
FileOutputStream fos = new FileOutputStream(file);
String car = "ferrari";
ObjectOutputStream os = new ObjectOutputStream(fos);
os.writeObject(app);
os.writeObject(car);
os.close();
here is my code(reading the class object from the file from extarnal storage):
File file = new File(Environment.getExternalStorageDirectory(), "savedData");
FileInputStream fis = new FileInputStream(file);
ObjectInputStream is = new ObjectInputStream(fis);
savedData = (SavedFriend) is.readObject();
String car = (String) is.readObject();
Toast.makeText(getApplicationContext(), car, Toast.LENGTH_LONG).show();
is.close();
i have written object in one class and read it from another class. as you can see, i have written a string (car) as object for test purpose and the class object. i have read them in another class. now the value of class object and string (car) are showing perfectly. that means they are written well in the file in external storage. but when i shut down my Nexux 7 (for testing the app) and run the app again, the value of string (car) is showing perfectly, but the values of the variables from the class object are showing null. what is the problem?
in my manifest i have added:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
by the way, the class's object i want to write as object implements Serializable .... even, i have implements Serializable for all classes for test . but it is not working.
i cannot use Database or other storage technique, because i have came a long way with this app so if i use other technique, i have to change most of my code. please help.
is it possible to write the object in phone's internal memeory? i have also write the file using getActivity().getApplicationContext().openFileOut() before. but i fetch the same problem with that approach.

How to request Android download manager to download multiple files at the same time. Also I would like to know each and every file download status.
Request the first one.
Then, request the second one.
Then, request the third one.
Continue as needed.
Whether they download "at the same time" is not your concern, nor do you have control over it. They will download when DownloadManager decides to download them, which may be simultaneously or not.
1. Register listener for download complete
IntentFilter intentFilter = new IntentFilter(
DownloadManager.ACTION_DOWNLOAD_COMPLETE);
registerReceiver(downloadReceiver, intentFilter);
2.Make request
Uri downloadUri = Uri.parse(entry.getValue());
DownloadManager.Request request = new DownloadManager.Request(
downloadUri);
request.setDestinationUri(path_to _file_store)));
downloadManager.enqueue(request);
3.Check status in listener
private BroadcastReceiver downloadReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context arg0, Intent intent) {
String action = intent.getAction();
if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
long downloadId = intent.getLongExtra(
DownloadManager.EXTRA_DOWNLOAD_ID, 0);
System.out.println("download id=" + downloadId);
CheckDwnloadStatus(downloadId);
}
}
};
private void CheckDwnloadStatus(long id) {
// TODO Auto-generated method stub
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterById(id);
Cursor cursor = downloadManager.query(query);
if (cursor.moveToFirst()) {
int columnIndex = cursor
.getColumnIndex(DownloadManager.COLUMN_STATUS);
int status = cursor.getInt(columnIndex);
int columnReason = cursor
.getColumnIndex(DownloadManager.COLUMN_REASON);
int reason = cursor.getInt(columnReason);
switch (status) {
case DownloadManager.STATUS_FAILED:
String failedReason = "";
switch (reason) {

break;
case DownloadManager.ERROR_UNHANDLED_HTTP_CODE:
failedReason = "ERROR_UNHANDLED_HTTP_CODE";
break;
case DownloadManager.ERROR_UNKNOWN:
failedReason = "ERROR_UNKNOWN";
break;
}
Toast.makeText(this, "FAILED: " + failedReason,
Toast.LENGTH_LONG).show();

Does android OS log system events to a log file somewhere? If so, where/how can I read this?
Background: After leaving my SEMC X10 Mini Pro on charge last night, I wake up to find it was off. I'd like to look in a log file to try and work out when and why the phone switched itself off.
