How to take a screenshot of a current Activity and then share it?
This is how I captured the screen and shared it.
First, get root view from current activity:
View rootView = getWindow().getDecorView().findViewById(android.R.id.content);
Second, capture the root view:
public static Bitmap getScreenShot(View view) {
View screenView = view.getRootView();
screenView.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(screenView.getDrawingCache());
screenView.setDrawingCacheEnabled(false);
return bitmap;
}
Third, store the Bitmap into the SDCard:
public static void store(Bitmap bm, String fileName){
final static String dirPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Screenshots";
File dir = new File(dirPath);
if(!dir.exists())
dir.mkdirs();
File file = new File(dirPath, fileName);
try {
FileOutputStream fOut = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.PNG, 85, fOut);
fOut.flush();
fOut.close();
} catch (Exception e) {
e.printStackTrace();
}
}
At last, share the screenshot of current Activity:
private void shareImage(File file){
Uri uri = Uri.fromFile(file);
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("image/*");
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "");
intent.putExtra(android.content.Intent.EXTRA_TEXT, "");
intent.putExtra(Intent.EXTRA_STREAM, uri);
try {
startActivity(Intent.createChooser(intent, "Share Screenshot"));
} catch (ActivityNotFoundException e) {
Toast.makeText(context, "No App Available", Toast.LENGTH_SHORT).show();
}
}
I hope you will be inspired by my codes.
UPDATE:
Add below permissions into your AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Because it creates and accesses files in external storage.
UPDATE:
Starting from Android 7.0 Nougat sharing file links are forbiden. To deal with this you have to implement FileProvider and share "content://" uri not "file://" uri.
Here is a good description how to do it.
How to take a screenshot and share it programmatically
Try this for taking screenshot of current Activity:
Android 2.2 :
private static Bitmap takeScreenShot(Activity activity)
{
View view = activity.getWindow().getDecorView();
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
Bitmap b1 = view.getDrawingCache();
Rect frame = new Rect();
activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);
int statusBarHeight = frame.top;
DisplayMetrics displaymetrics = new DisplayMetrics();
mContext.getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int width = displaymetrics.widthPixels;
int height = displaymetrics.heightPixels;
Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height - statusBarHeight);
view.destroyDrawingCache();
return b;
}
private static void savePic(Bitmap b, String strFileName)
{
FileOutputStream fos = null;
try
{
fos = new FileOutputStream(strFileName);
if (null != fos)
{
b.compress(Bitmap.CompressFormat.PNG, 90, fos);
fos.flush();
fos.close();
}
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
}
take screenshot from layout and share via android
Please use this code this is tested code :
public static void takeScreenshot(Context context, View view) {
String path = Environment.getExternalStorageDirectory().toString() +
"/" + "test.png";
View v = view.findViewById(android.R.id.content).getRootView();
v.setDrawingCacheEnabled(true);
v.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(v.getDrawingCache());
v.setDrawingCacheEnabled(false);
OutputStream out = null;
File imageFile = new File(path);
try {
out = new FileOutputStream(imageFile);
// choose JPEG format
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
} catch (FileNotFoundException e) {
// manage exception
} catch (IOException e) {
// manage exception
} finally {
try {
if (out != null) {
out.close();
}
} catch (Exception exc) {}
}
// onPauseVideo();
Intent share = new Intent(Intent.ACTION_SEND);
share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(imageFile));
share.setType("image/png");
((Activity) context).startActivityForResult(
Intent.createChooser(share, "Share Drawing"), 111);
}
How to programmatically take a screenshot of open current activity in Android?
1-Create layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/relativelayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="@+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp"
android:text="Create ScreenShot" />
<ImageView
android:id="@+id/sowscreenshot"
android:layout_width="216dp"
android:layout_height="360dp"
android:layout_below="@+id/btn"
android:layout_centerHorizontal="true"
android:layout_marginTop="10dp" />
</RelativeLayout>
2-Create Activity
import android.graphics.Bitmap;
import android.graphics.drawable.BitmapDrawable;
import android.os.Bundle;
import android.os.Environment;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
public class MainActivity extends AppCompatActivity {
Button btn_screenshoot;
int i = 0;
ImageView imgv_showscreenshot;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imgv_showscreenshot = (ImageView) findViewById(R.id.showscreenshot);
btn_screenshoot = (Button) findViewById(R.id.btn);
btn_screenshoot.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
View view = findViewById(R.id.relativelayout);
view.setDrawingCacheEnabled(true);
Bitmap bitmap = view.getDrawingCache();
BitmapDrawable bitmapDrawable = new BitmapDrawable(bitmap);
// set screenshot bitmapdrawable to imageview
imgv_showscreenshot.setBackgroundDrawable(bitmapDrawable);
if (Environment.MEDIA_MOUNTED.equals(Environment
.getExternalStorageState())) {
// we check if external storage is available, otherwise
// display an error message to the user using Toast Message
File sdCard = Environment.getExternalStorageDirectory();
File directory = new File(sdCard.getAbsolutePath()
+ "/ScreenShots");
directory.mkdirs();
String filename = "screenshot" + i + ".jpg";
File yourFile = new File(directory, filename);
while (yourFile.exists()) {
i++;
filename = "screenshot" + i + ".jpg";
yourFile = new File(directory, filename);
}
if (!yourFile.exists()) {
if (directory.canWrite()) {
try {
FileOutputStream out = new FileOutputStream(
yourFile, true);
bitmap.compress(Bitmap.CompressFormat.PNG, 90,
out);
out.flush();
out.close();
Toast.makeText(
MainActivity.this,
"File exported to /sdcard/ScreenShots/screenshot"
+ i + ".jpg",
Toast.LENGTH_SHORT).show();
i++;
} catch (IOException e) {
e.printStackTrace();
}
}
}
} else {
Toast.makeText(MainActivity.this,
"Sorry SD Card not available in your Device!",
Toast.LENGTH_SHORT).show();
}
}
});
}
}
3-Add permission to Manifest file
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
current activity screen shot and share it with share icon in action bar
Here is the code that allowed my screenshot to be stored on sd card and used later for whatever your needs are:
First, add proper permission to save file:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
And this is the code (running in an Activity):
private void takeScreenshot() {
Date now = new Date();
android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);
try {
// image naming and path to include sd card appending name you choose for file
String mPath = Environment.getExternalStorageDirectory().toString() + "/" + now + ".jpg";
// create bitmap screen capture
View v1 = getWindow().getDecorView().getRootView();
v1.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);
File imageFile = new File(mPath);
FileOutputStream outputStream = new FileOutputStream(imageFile);
int quality = 100;
bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
outputStream.flush();
outputStream.close();
openScreenshot(imageFile);
} catch (Throwable e) {
// Several error may come out with file handling or OOM
e.printStackTrace();
}
}
And this is how you can open the recently generated image:
private void openScreenshot(File imageFile) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Uri uri = Uri.fromFile(imageFile);
intent.setDataAndType(uri, "image/*");
startActivity(intent);
}

Taking a screenshot, then store in external storage, then share
Well I was stuck in external storage permission.
After applying this answer, I got it now. Appreciate stackoverflow so much!

How to programmatically take a screenshot on Android?
Here is the code that allowed my screenshot to be stored on an SD card and used later for whatever your needs are:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
And this is the code (running in an Activity):

android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);
try {
// image naming and path to include sd card appending name you choose for file
String mPath = Environment.getExternalStorageDirectory().toString() + "/" + now + ".jpg";
// create bitmap screen capture
View v1 = getWindow().getDecorView().getRootView();
v1.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);
File imageFile = new File(mPath);
FileOutputStream outputStream = new FileOutputStream(imageFile);
int quality = 100;
bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
outputStream.flush();
outputStream.close();
openScreenshot(imageFile);
} catch (Throwable e) {
// Several error may come out with file handling or DOM
e.printStackTrace();
}
}
And this is how you can open the recently generated image:
private void openScreenshot(File imageFile) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Uri uri = Uri.fromFile(imageFile);
intent.setDataAndType(uri, "image/*");
startActivity(intent);
}
If you want to use this on fragment view then use:
View v1 = getActivity().getWindow().getDecorView().getRootView();
instead of
View v1 = getWindow().getDecorView().getRootView();
on takeScreenshot() function
Note:
This solution doesn't work if your dialog contains a surface view. For details please check the answer to the following question:
