This is a piece of code. Am trying to save the images in the folder after enter the details like name, age, gender. but if i am not entering any thing and just take the image it will save the image into a null folder. I dont want this to happen. When details are not entered it should not save the image any where and it should show a message like please enter the data. Can anyone help why it is saving the data yo a null folder


Use Validation bro.
if (edt.getText().toString().length() <= 0) {
edt.setError("Please Enter Name/Name Required.");
valid_name = null;
} else if (!edt.getText().toString().matches("[a-zA-Z ]+")) {
edt.setError("Accept Alphabets Only.");
valid_name = null;
} else {
valid_name = edt.getText().toString();
}

Memory usage increases with every reload of intent in Android. Why?

I have an activity/intent in which a text file (which contains a JSON array) is read from the device.
On every reload another row from the array is being processes.
The text file isn't that large (20 Kb) and is being downloaded in the MainActivity together with some images (up to 50) which are between 20 and 70 Kb.
Everytime the intent is reloaded and another row is processes, another image is being loaded into an ImageView. Also several TextViews are updated with Strings that are read from the JSON array.
The issue is that with every reload of the intent, the memory usage increases with about 1 Mb.
I show this through the use of:
Runtime runtime = Runtime.getRuntime();
long usedMemory=runtime.totalMemory() / (1024 * 1024);
The Bitmap is recycled,
BufferedWriter is closed,
FileInputStream is closed,
BufferedReader is closed and
InputStreamReader is closed
What am I missing that causes the memory usage to increase?
This is the code form the Activity:

I think your activity just got restarted you need to put below code in manifest where you declare. and save your uri on saveInstanceState and restore it on onrestoreinstancestate. it will be resolve your issue
android:configChanges="orientation|keyboardHidden|screenSize"

Use this lib,Provides support above API 14

cant find audiofile when recording sound

My Problem is, that I capture audio by pressing the record button, but I can't see any audioFile in the specific path.
I capture sound, when I press the capture button:
private void startRecord()
{
ImageButton soundStop = (ImageButton)findViewById(R.id.soundstop);
soundStop.setVisibility(View.VISIBLE);
mediaRecorder = new MediaRecorder();
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
//mediaRecorder.setOutputFormat(sound);
//mediaRecorder.setOutputFile(soundFilePath);
//mediaRecorder.setAudioEncoder(audioEncoder);
//Log.d("hier ", "hier" + soundFilePath);
try {
mediaRecorder.prepare();
mediaRecorder.start();
}catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Toast.makeText(getApplicationContext(), "Aufnahme gestartet", Toast.LENGTH_LONG).show();
}
When I press the Stop Recording Button the file should be saved in the specific path. I tried it with Directory Musik and Downloads, but I can't find any file there
final OnClickListener soundRecordStop = new OnClickListener(){
#Override
public void onClick(View v) {
soundStop();
}
};
public void soundStop(){
SimpleDateFormat sdf = new SimpleDateFormat("dd.MM.yyyy hh:mm:ss");

String actualTime = sdf.format(time);
SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);
String name = sharedPreferences.getString("soundformat", "format");
int audioEncoder = sharedPreferences.getInt("audioEncoder", Property.getAudioEncoderInt());
String dateiendung = ".aac";
int sound = 6;
if(name == "aac"){
dateiendung = ".aac";
sound = 6;
} else if(name == "amr_nb"){
dateiendung = ".3gp";

}
else if( name == "mpeg"){
dateiendung = ".mp4";
sound = 2;
}
else if( name == "gpp" ){
Log.d("in gpp", "in gpp");
dateiendung = ".3gp";
sound = 1;
}
soundFile = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
soundFilePath = soundFile.getAbsolutePath() + actualTime + dateiendung;
Log.d("hier ", "hier1" + mediaRecorder);
if(mediaRecorder != null){
Log.d("hier ", "hier2" + mediaRecorder);
try {
//mediaRecorder.prepare();
mediaRecorder.stop();
mediaRecorder.release();
//mediaRecorder = null;
Log.d("hier ", "hier4" + mediaRecorder);
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
mediaRecorder.setOutputFormat(sound);
mediaRecorder.setOutputFile(soundFilePath);
Log.d("hier ", "hier2");
String pfad = soundFile.getAbsolutePath();
Toast.makeText(getApplicationContext(), "Aufnahme in " + pfad + " gespeichert", Toast.LENGTH_LONG).show();
ImageButton soundStop = (ImageButton)findViewById(R.id.soundstop);
soundStop.setVisibility(View.INVISIBLE);
}
The path seems to be correct: pfad /storage/sdcard0/Download17.07.2014 11:55:58.aac
Thanks for the comment the missing File Separator wasn't intentionally. I insert the missing Separator in Order to save the audio File in Downloads Directory. But no File nevertheless 😑
Please help me to find my file ;)

intent.putExtra("email", Email);
intent.putExtra("website", Website);
intent.putExtra("title", Title);
startActivity(intent);
SecondActivity is to write this data into .csv file:
public class CSV {
private PrintWriter csvWriter;
private File file;
public CSV(File file) {
this.file = file;
}
public void writeHeader(String data) {
try {
if (data != null) {
csvWriter = new PrintWriter(new FileWriter(file, true));
csvWriter.print("\r\n"+",");
csvWriter.print(data);
csvWriter.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}}
File in directory is successfully created and data is inserted. I am trying to check the data like Name or Email, if it is duplicate/already recorded to not save into .csv and warn user with Toast "same data".
I think it is something to do with line:
try {
if (data != null) {
Your helps and suggestions are appreciated. Thank you.

Use following function
public boolean exist(String newData){
try {
FileInputStream fIn = new FileInputStream(file);
BufferedReader myReader = new BufferedReader(
new InputStreamReader(fIn));
String aDataRow = "";
String aBuffer = "";
while ((aDataRow = myReader.readLine()) != null) {
if(aDataRow.contains(newData))//<--check if data exists
return true;
}
txtData.setText(aBuffer);
myReader.close();
} catch (Exception e) {
}
return false;
}
And change your write header function to:
public void writeHeader(String data) {
try {
if (data != null&&!data.isEmpty()&&!exist(data)) {
csvWriter = new PrintWriter(new FileWriter(file, true));
csvWriter.print("\r\n"+",");
csvWriter.print(data);
csvWriter.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}

data != null doesnt cover the case that the String is just empty, but not null. So basically you get "" from the textview by calling getText(). adding && !"".equals(data) should fix that problem
UPDATE
Well, there is a difference between an empty, and an uninitalized String. An uninitalized String means you declared it like String a; but nothing further.
If you use editText.getText() the editText will return a String which has been initialized but contains only what is currently in it. So basically if there is nothing in the editext it will return "".
And to sum this up:
String a;
null == "" // false
a == null // true
"".equals(editText.getTExt()) // true if the editext doesnt contain anything
