My app is to open the built in camera and save it into sd card then start a new activity and preview the captured image on it.
This is the loginActivity that start a new AsynTask to open the camera :

And this is the AsynTask :-

}
and this is the previewActivity:-

}
};
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
previewIV.setImageBitmap(BitmapFactory.decodeFile(path));
}
}
}
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.preview);
path = getIntent().getExtras().getString("path");
previewIV = (ImageView) findViewById(R.id.previewPicID);
previewIV.setImageBitmap(AndroidImage.decodeSampledBitmapFromSDcard(
path, 150, 150));
// previewIV.setImageBitmap(AndroidImage.readImage(path));
Button process = (Button) findViewById(R.id.processID);
process.setOnClickListener(processOnClickListener);
Button back = (Button) findViewById(R.id.back);
back.setOnClickListener(backOnClickListener);
}
}
The error that appear that sometimes when take picture it appear in the previewActivity and
sometime doesn't appear ?
Why that error
??

I am facing an issue which I do not understand. I am taking a picture then creating a PNG image file as per code that follows but somewhere down the line a random string is being added to the filename which causes me all sorts of issues. For example (as per tutorials I have found): I create an image called dimage_(generated timestamp) and save the string to shared preferences and the image in getExternalFilesDir(Environment.DIRECTORY_PICTURES). In shared preferences the string is correct but the file has the above mentioned string appended.
Eg:
The generated filename string saved in shared prefs:
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<string name="driver_picture">dimage_20190610_065509</string>
</map>
Whereas the file checked with adb results as:
127|generic_x86:/storage/emulated/0/Android/data/africa.mykagovehicledrivers/files/Pictures $ ls
dimage_20190610_0655091215099619.png
generic_x86:/storage/emulated/0/Android/data/africa.mykagovehicledrivers/files /Pictures $
I have no clue where the 1215099619 extra part comes from!
This is the code of the activity:

As per code I am using String imageFileName; to save the path and then use it in the button click action to save it into shared preferences.
Thanks!
Found out the reasin. createTempFile does this. Switched to new File() and this solved the issue.
I have 2 activity, Tambah and Tampil activity.
I use Tambah activity to add new data (form and button submit), and after submit, it will move to Tampil activity. in Tampil activity will show the list view of data (i'm using Volley). all script works, no error. but in Tampil activity only showing old data (like before add), not showing the newest data.

how can when Intent from Tambah activity to Tampil activity, the Tampil activity reload all data include newest data)?
It seems that you are not waiting until data is uploaded and redirecting to next screen.
Try this answer
Implementing ProgressDialog in Multipart Upload Request
onCompleted redirect to next screen
I am making an app with various activities and each activity uses the camera function which is defined in another class. I want that in each activity when the camera button is clicked the camera class is called.
This is my main class:-
package com.example.ishan.complainbox;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import java.lang.String;
public class Crime extends MainActivity implements View.OnClickListener
{
camera cam=new camera();
EditText str,city,pn,det;
Button save,pic;
crimeDBHandler dbHandler;
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_crime);
// Get References of Views
str = (EditText) findViewById(R.id.str);
city = (EditText) findViewById(R.id.city);
pn = (EditText) findViewById(R.id.pin);
det = (EditText) findViewById(R.id.detail);
save = (Button) findViewById(R.id.save);
pic=(Button) findViewById(R.id.uploadpic);
dbHandler = new crimeDBHandler(this, null, null, 1);
}
public void onClick(View view) {
String street = str.getText().toString();
String cty = city.getText().toString();
String pin = pn.getText().toString();
String detail = det.getText().toString();
// check if any of the fields are vaccant
if(str.equals("")||city.equals("")||pn.equals("")||det.equals(""))
{
Toast.makeText(getApplicationContext(), "Field Vacant",
Toast.LENGTH_LONG).show();
return;
}
// check if both passwords match
else
{
// Save the Data in Database
dbHandler.insertEntry(street,cty,pin,detail);
Toast.makeText(getApplicationContext(), "Complaint Successfully
Filed ", Toast.LENGTH_LONG).show();
}
}
};

This can be achieved through regular inter-activity communication mechanisms like passing intents or using broadcast receivers. I would suggest using intents - Refer this basic example from Android doc: https://developer.android.com/training/basics/firstapp/starting-activity.html
EDIT
Response to OP's question in comment-
You have to save the image file to FS in your Camera Class and pass the file name as an Extra with the intent to your Crime class. Since you are dealing with storage your Apps's manifest now would need additional permissions. I would recommend you go through this thread: Camera is not saving after taking picture

Consider using one Android's default external storage folders, in your case the DIRECTORY_MUSIC like this
File path = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_MUSIC);
You can use this File class constructor to create a new folder on the SD card:
File audioFolder = new File(Environment.getExternalStorageDirectory(),
"newaudiofolder")
if (!audioFolder.exists()) {
boolean success = audioFolder.mkdir()
if (success) {
// save the file
}
}
This class call the camera class which click the photo but on activity result of this class it gives error on line 41.
package com.example.fish;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.Window;
import android.widget.ImageView;
import com.non_activity.*;
public class Camera extends Activity
{
ImageView image;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
//setContentView(R.layout.name_image);
image=(ImageView)findViewById(R.id.cameraImage);
Intent in= new Intent(this,com.camera.CameraCall.class);
startActivityForResult(in, 1);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == 1)
{
ImageRotation ri= new ImageRotation();
image.setImageBitmap(ri.getImageOrientation(com.camera.Camera_nonClass.getPath(), 7)); //line 41
}

This is the actual camera code application which actually clicks the photo from camera
and return the result back to the calling camra class.

This is the file which store the path of image taken from camra.

public static String getPath() {
return path;
}
public static void setPath(String path) {
