I'm trying to download pictures in the background of an app using Service (not IntentSevice)
Somehow, my code doesn't work.
I set permissions for Internet and Storage in the Manifest.
I'm thankful for any comments or answers (:
Here's my code:
For the Service and then for the MainActivity
i have already tried different links or httpURLConnection instead of the normal URL connection but that doesnt't work either.
when I run the app, it always shows my "error" toast. it doesn't even get to the Input Stream.
public class Download extends Service {
public static final String URL = "url";

I'm fetching user's profile picture from facebook and I want to send it to ProfileActivity.java so that it can be displayed on user profile.
The problem is that the image is not getting sent from SignUpScreen.java to ProfileActivity.java. Though I am able to send name & email from one to another.
Here's SignUpScreen.java file's code:
public class SignUpScreen extends AppCompatActivity {
Button facebookLoginButton;
CircleImageView mProfileImage;

mProfileImage = (CircleImageView) findViewById(R.id.user_profile_image);
mUsername = (TextView) findViewById(R.id.userName);
mEmailID = (TextView) findViewById(R.id.aboutUser);
mFbProfile = Profile.getCurrentProfile();
//mUsername.setVisibility(View.INVISIBLE);
//mEmailID.setVisibility(View.INVISIBLE);

} else {

}
}
});
}
});
}
public void saveNewUser() {

user.setUsername(name);
user.setEmail(email);
user.setPassword("hidden");
user.signUpInBackground(new SignUpCallback() {

startActivity(profileIntent);
} catch (JSONException e) {

}
}
});
Bundle parameters = new Bundle();

}
return null;
}
#Override

Here's ProfileActivity.java file's code:
public class ProfileActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_profile);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Bundle bundle = getIntent().getExtras();
CircleImageView mProfileImage = (CircleImageView) findViewById(R.id.user_profile_image);
TextView mUsername = (TextView) findViewById(R.id.userName);
TextView mEmailID = (TextView) findViewById(R.id.aboutUser);
Bitmap bitmap = (Bitmap) getIntent().getParcelableExtra("user_pic");
mProfileImage.setImageBitmap(bitmap);
mUsername.setText(bundle.getString("userName"));
mEmailID.setText(bundle.getString("userEmail"));
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
}
Please let me know what is going wrong here.
In your getUserDetailsFromFacebook() method you have called new ProfilePicAsync().execute(userID) to get the image. But it seems that before you could fetch the image ,startActivity(profileIntent) probably gets called.
First be sure that you have fetched the image from facebook before you call startActivity(profileIntent).
EDIT
Add this to your getUserDetailsFromFacebook() ,
b.putString("userName", name);
b.putString("userEmail", email);
profileIntent.putExtras(b);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
profileIntent.putExtra("user_pic", byteArray);
startActivity(profileIntent);
Add this to your ProfileActivity.java ,
byte[] byteArray = getIntent().getByteArrayExtra("user_pic");
Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
mProfileImage.setImageBitmap(bmp);
This is not a right way to pass image from Activity to Activity within same application. You can easily send the path by intent and load it into other Activity.
To save a bitmap in Activity A, use
FileOutputStream out = null;
try {
out = new FileOutputStream(FILENAME); //FILENAME is your defined place to store image
bmp.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
Now you have FILENAME global string which is accessible from Activity B.
Just load it where its needed.
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap bitmap = BitmapFactory.decodeFile(FILENAME, options);
mProfileImage.setImageBitmap(bitmap);
it works for me.
OneActivity.java
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
Intent intent = new Intent(StartPage.this, SecondActivity.class);
Toast.makeText(StartPage.this, "You have setted this wallpaper for Monday", Toast.LENGTH_LONG).show();
intent.putExtra("pic", byteArray);
//intent.putExtra("resourseInt", bm);
startActivity(intent);
SecondActivity.Java
byte[] byteArray;
Bitmap bmp,
byteArray = getIntent().getByteArrayExtra("pic");
bmp1 = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
myWallpaperManager.setBitmap(bmp);
im adding a camera scanning facility to a project of mine. Im using the following github https://github.com/jhansireddy/AndroidScannerDemo project

when this is the config nothing happens when you press the button.
its driving me mad, please help
Your onClick method doesn't launch the activity, it just creates the intent. Try this:
imgCamera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(context, ScanAdaptor.class);
((Activity) context).startActivity(intent);
}
}
