I am trying to add a share button to my app which takes the screenshot of screen and then shares it via Facebook etc. I have searched over internet. I also have searched Stack Overflow too; there are many threads related with this issue but I couldn't figure that out yet. What is confusing me is .. In every example the image's filepath is hardcoded. I did like that but it is not useful and dynamic. What I am trying to do is to take the screenshot of that moment and then share it, but when I give the filepath by myself it just takes that picture from a folder and shares that
public void clickButton(View v) {
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
//set the type
shareIntent.setType("image/png");
//add a subject
shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,
"CAR EXAMPLE");
//build the body of the message to be shared
String shareMessage = "An app...";
//add the message
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareMessage);
//add the img
shareIntent.putExtra(Intent.EXTRA_STREAM,
Uri.parse("/storage/sdcard0/Tutorial_ScreenShot/screenshot0.jpg"));
//start the chooser for sharing
startActivity(Intent.createChooser(shareIntent, "Share"));
}
As you can see in the add image part I give the filepath by myself. So how to give a more dynamic behaviour to that .. I mean when I click the button my app's screen has to be saved in a folder and then I can share that without hardcoding its filepath.
Edited: After trying the solution below;
Well, thanks. I've called shareIt() right under onClick of a button it and application stops... Here is the log.
