I am using Volley to download a file from AWS. The file size is around 6 mb. In Android docs it is mentioned you should not download a large file using Volley. So what is the limit to the file size on Volley. I am using different network type and signal strength on emulator to check how my app behaves while downloading the file. I mainly want to check for GSM network type. If i keep Network type as GSM and even if my signal strength is great, i am getting timeout. If my Network Type is Full or LTE, the file gets downloaded very quickly. For GSM i even increased the retry limit to 5 minutes but still it gives me timeout. I dont want to allow the retry policy to be grater than 10 seconds. Here is my code.
public class MainActivity extends AppCompatActivity {
InputStreamVolleyRequest request;
private TextView textView;
private Button button;
//private RequestQueue requestQueue;
//WifiManager wifiManager;
long FILE_SIZE ;
long startTime;
long endTime;
private long takenTime;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = findViewById(R.id.tv);
button = findViewById(R.id.button);
String mUrl="my url";
// wifiManager = (WifiManager) getApplicationContext().getSystemService(WIFI_SERVICE);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startTime = System.currentTimeMillis();
textView.setText("");
MySingleton.getMySingleton(getApplicationContext()).addToRequestQueue(request);
// requestQueue.add(request);
button.setEnabled(false);
}
});
// requestQueue = Volley.newRequestQueue(getApplicationContext());
request = new InputStreamVolleyRequest(Request.Method.GET, mUrl, new Response.Listener<byte[]>() {
@Override
public void onResponse(byte[] response) {
if(response!=null){
FileOutputStream outputStream;
String name = "justdownloaded.mp3";
try {
outputStream = openFileOutput(name, Context.MODE_PRIVATE);
outputStream.write(response);
outputStream.close();
Toast.makeText(MainActivity.this, "Download complete.", Toast.LENGTH_LONG).show();
textView.setText("Complete");
endTime = System.currentTimeMillis();
File file1 = new File(getApplicationContext().getFilesDir().getAbsolutePath(),name);
Log.i("TAG", "onResponse: "+MD5.calculateMD5(file1));
boolean b =MD5.checkMD5(request.responseHeaderETag,file1);
Log.i("TAG", "onResponse: "+b);
FILE_SIZE = file1.length();
int fileSize = (int) (FILE_SIZE / 1024);
takenTime = endTime - startTime;
double s = (double) takenTime / 1000;
double speed = fileSize / s;
Log.i("TAG", "onResponse: "+new DecimalFormat("##.##").format(speed)
+ "kb/second"+fileSize);
} catch (Exception e) {
e.printStackTrace();
}
button.setEnabled(true);
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
if(error != null){
if(error.getClass().equals(TimeoutError.class)){
Toast.makeText(getApplicationContext(),"Time Out Error",Toast.LENGTH_LONG).show();
}
}
endTime = System.currentTimeMillis();
// Toast.makeText(MainActivity.this, "Error", Toast.LENGTH_SHORT).show();
Log.i("TAG", "onErrorResponse: "+error.networkResponse);
Log.i("TAG", "onErrorResponse2: "+error.getLocalizedMessage());
Log.i("TAG", "onErrorResponse3: "+error.getMessage());
Log.i("TAG", "onErrorResponse4: "+error.getNetworkTimeMs());
Log.i("TAG", "onErrorRespons5: "+error.getCause());
Log.i("TAG", "onErrorRespons6: "+error.getStackTrace().toString());
takenTime = endTime - startTime;
button.setEnabled(true);
textView.setText("Error");
double s = (double) takenTime / 1000;
double speed = FILE_SIZE / s;
Log.i("TAG", "onResponse: "+new DecimalFormat("##.##").format(speed) + "kb/second");
}
});
request.setRetryPolicy(new DefaultRetryPolicy(8000,
2,
2));
}
}
All the log statements in the error listener returns null. I am able to see the TimeOut toast for GSM. Is it possible to do this for GSM using Volley instead of Download Manager? I can't use Retrofit as client's requirement is Volley What should i do differently for efficient download of file from server using GSM in minimum time
