I put Signatureview inside Android Scrollview.
But while writing something on SignatureView, scrolling up and down I'm not able to write my sign.
How to Disable the Scrollview when SignatureView is touched

when you want to sign you need to intercept the scroll event when the signature is touched. and when you are outside of the signature area turn back the normal status: the scrollView intercept the scroll event.
inside onCreate in your controller add the following :
signatureView.setOnTouchListener(new View.OnTouchListener(){
#Override
public boolean onTouch(View view, MotionEvent motionEvent) {
int action = motionEvent.getAction();
switch (action){
case MotionEvent.ACTION_DOWN:
// Disable the scroll view to intercept the touch event
scrollView1.requestDisallowInterceptTouchEvent(true);
return false;
case MotionEvent.ACTION_UP:
// Allow scroll View to interceot the touch event
scrollView1.requestDisallowInterceptTouchEvent(false);
return true;
case MotionEvent.ACTION_MOVE:
scrollView1.requestDisallowInterceptTouchEvent(true);
return false;
default:
return true;
}
}
});

You have to intercept touch events in this SignatureView. The best approach is to subclass it and override onTouchEvent:
public class MySignatureView extends SignatureView {
#Override
public boolean onTouchEvent(MotionEvent event) {
// intercept touch event here, so it's not passed to ScrollView
super.onTouchEvent(event);
return false;
}
}
And then, of course change SignatureView to MySignatureView in your layout.
<com.your.package.name.MySignatureView
xmlns:sign="http://schemas.android.com/apk/res-auto"
android:id="#+id/signature_view"
android:layout_width="match_parent"

android:minHeight="250dp"
android:layout_weight="1"
sign:penSize="5dp"
sign:backgroundColor="#ffffff"
sign:penColor="#000000"
sign:enableSignature="true"/>

Include this permission in manifest if you are storing pdf in external storage.
Use Asset folder like this
AssetManager assetManager = getAssets();
File file = new File(getFilesDir(), "xyz.pdf");
in = assetManager.open("xyz.pdf");
out = openFileOutput(file.getName(), Context.MODE_WORLD_READABLE);
copyFile(in, out);
in.close();
in = null;
out.flush();
out.close();
out = null;

You can open it as an input stream like this from a fragment
reader = new BufferedReader(new InputStreamReader(getActivity().getAssets().open(myfile.pdf))
You don't need permisssions as you're accessing your app's internal files but putting pdf into assets can increase the weight of the app , be careful
and then you can save it as string like that
private StringBuilder text = new StringBuilder();
String mLine;
while ((mLine = reader.readLine()) != null) {
text.append(mLine);
text.append('\n');
}
if (reader != null) {
try {
reader.close();
} catch (IOException e) {
//log the exception
}

});
// tv = (TextView)findViewById(R.id.testText);
// tv.setText(Environment.getExternalStorageDirectory().getAbsolutePath());
//
// Toast toast = Toast.makeText(getApplicationContext(),Environment.getExternalStorageDirectory().getAbsolutePath(),Toast.LENGTH_LONG);

}
private void render() {
try {
imageView = (ImageView)findViewById(R.id.imageView);
int REQ_WIDTH = 1;
int REQ_HEIGHT = 1;
REQ_WIDTH = imageView.getWidth();
REQ_HEIGHT = imageView.getHeight();
Bitmap bitmap = Bitmap.createBitmap(REQ_WIDTH, REQ_HEIGHT, Bitmap.Config.ARGB_4444);
File file = new File(Environment.getDataDirectory().getPath()+"Adobe Reader/answerkey.pdf");
PdfRenderer pdfRenderer = new PdfRenderer(ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY));
if(currentPage < 0) {
currentPage=0;
}
else if (currentPage > pdfRenderer.getPageCount()) {
currentPage = pdfRenderer.getPageCount()-1;
}

For some reason, the PDF just isn't being displayed on screen, I keep getting a white, blank background. What am I doing wrong? Is the path incorrect? I have no SD card on my device. Or am I doing something wrong with the bitmap?

Is the path incorrect?
Yes.
I have no SD card on my device
That is fine. That would be removable storage. I am interpreting "Download/Adobe Reader/answerkey.pdf" as referring to something on external storage.
The recommended way to get this location would be to replace:
File file = new File(Environment.getDataDirectory().getPath()+"Adobe Reader/answerkey.pdf");
with:
File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), "Adobe Reader/answerkey.pdf");
Note that your app will need to request the READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE permission, and that will involve runtime permissions on Android 6.0+ (if your targetSdkVersion is 23 or higher).

Share text and image with android intent

That is my code java
intent.putExtra(Intent.EXTRA_SUBJECT, "My App name and some text");
intent.putExtra(Intent.EXTRA_TEXT, "a link");
intent.putExtra(Intent.EXTRA_STREAM,getImageUri(context,mBitmap));
intent.setType("image/*,text/plain");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
I want to share image and text. This code works on WhatsApp, Twitter, Gmail , etc .. but it does not work on Facebook
thank you in advance for your help

If you want to share the Image and text on Facebook without using Facebook SDK then you have to create the bitmap of your image plus text and then you can share that bitmap on facebook.
Download the source code from here (Share image and text on facebook using intent in android)

You can share int value of an image as R.drawable.image and get it with getResources.getDrawable(int)

Unable to take fullscreen screenshot

I wanted to make my app be able to take proper screenshots like my own device does on touch of a button but it appears that it just takes screenshot of the view. What I want is to be able to take full screenshots with whatever it is on the screen like my device does.
Here's my java code:
package com.arvisapps.lazyscreenshot;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.graphics.Bitmap;
import android.graphics.drawable.BitmapDrawable;

NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
private void showNotification() {
builder.setAutoCancel(false);
builder.setContentTitle("Take Screenshot");
builder.setContentText("");
builder.setSmallIcon(R.drawable.ic_notification);
builder.setOngoing(true);
Notification notification = builder.build();
NotificationManager manager = (NotificationManager) this.getSystemService(NOTIFICATION_SERVICE);
manager.notify(1, notification);
}
private void dontShowNotification(){

nMgr.cancel(1);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
R1 = (RelativeLayout) findViewById(R.id.relatv);
CheckBox cb1 = (CheckBox) findViewById(R.id.cb_1);
cb1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked == true) {
showNotification();
} else if (isChecked == false) {
dontShowNotification();
}
}
});
}
public void takeScreenshot(View v)
{
View v1 = R1.getRootView();
v1.setDrawingCacheEnabled(true);
Bitmap bm = v1.getDrawingCache();
BitmapDrawable bmDrawable = new BitmapDrawable(bm);
img = (ImageView) findViewById(R.id.screenshots);
img.setBackgroundDrawable(bmDrawable);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

If your phone is rooted try.
Process sh = Runtime.getRuntime().exec("su", null,null);
OutputStream os = sh.getOutputStream();
os.write(("/system/bin/screencap -p " + "/sdcard/img.png").getBytes("ASCII"));
os.flush();
os.close();
sh.waitFor();
then read img.png as bitmap and convert it jpg as follows
Bitmap screen = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory()+
File.separator +"img.png");
//my code for saving
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
screen.compress(Bitmap.CompressFormat.JPEG, 15, bytes);
//you can create a new file name "test.jpg" in sdcard folder.
File f = new File(Environment.getExternalStorageDirectory()+ File.separator + "test.jpg");
f.createNewFile();
//write the bytes in file
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
// remember close de FileOutput
fo.close();

The method you're using, getDrawingCache() will only get that view's drawing cache. Unfortunately, an application cannot directly access the framebuffer (and thus the raw pixels) unless your device is rooted so you won't be able to take a full screenshot from your app.

How i can fit to all devices. Can anyone help?? Thanks in advance.

There are couple of possibilities:
use different xml files for different sizes of screen -> check here http://developer.android.com/guide/practices/screens_support.html
you may use scrollview -> http://developer.android.com/reference/android/widget/ScrollView.html
or simply make your layout fit to the smallest screen size you like to support and then just have "a little" unused space on the larger screens.
It really depends on what you need. Probably the most compatible and advanced solution would be 1.
BUT be aware of the fact that EVERY change on the screen layout has to be duplicated for each xml file following this route!

create xml for each device separately. follow this
second way:
create a parent LinearLayout and pass it to the following method
public static boolean isTabletPC(Context context) {
Display display = ((WindowManager) context
.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
if (display.getWidth() >= 1200) {
isTabletPC = true;
return isTabletPC;
} else {
isTabletPC = false;
return isTabletPC;
}
}
public static void fixUiDeviceDependencies(
Activity act, LinearLayout llParent) {
if (Utilities.isTabletPC(act)) {
Display display = ((WindowManager) act
.getSystemService(Context.WINDOW_SERVICE))
.getDefaultDisplay();
LayoutParams params = (LayoutParams) llParent
.getLayoutParams();
params.width = display.getWidth() / 2;
llParent.setLayoutParams(params);
}
}
