I have been trying to fix this error for a week now, but still cannot find the problem. The LogIn is working, but for some reason the share to Messenger Crashes. I cannot really understand what the problem is. Basically I save a text to speech to my device and then I attempt to share it. The file saves to the device (I checked), but messenger does not share.
Here is my code for sharing:
public void shareFile(View view) {
String sayWhat = "This is what you sound like when you write to me, thanks to the app Messenger Say it! Available now at Google Play";
HashMap hashmap = new HashMap();
hashmap.put("utteranceId", sayWhat);
String location = new StringBuilder(Environment.getExternalStorageDirectory().toString()).append("/").append(name).append(".mp3").toString();
speed = ((float)speedS.getProgress()/100F)*2.0F;
pitch=((float)pitchS.getProgress()/100F)*2.0F;
ttsread.setPitch(pitch);
ttsread.setSpeechRate(speed);
ttsread.synthesizeToFile(sayWhat, hashmap, location);
String mimeType = "audio/mpeg";
Uri contentUri = Uri.parse(location);
text.setText(contentUri.toString());
long futuretime = System.currentTimeMillis() + 1000;
while (System.currentTimeMillis() < futuretime) {
synchronized (this) {
try {
wait(futuretime - System.currentTimeMillis());
} catch (Exception e) {
}
}
}
ShareToMessengerParams params = ShareToMessengerParams.newBuilder(contentUri, "audio/mpeg")
.setMetaData("com.facebook.sdk.ApplicationId")
.build();
MessengerUtils.shareToMessenger(this, 1, params);
//MessengerUtils.finishShareToMessenger(activity,params);
}
and my logcat:

You need to read your logcat and try and understand what it is telling you.
java.lang.IllegalStateException: Could not execute method of the activity
OK...why?
Caused by: java.lang.reflect.InvocationTargetException
This just means it failed to invoke the target method - so pretty much the same as the first message. Still..why?
Caused by: java.lang.IllegalArgumentException: Unsupported URI scheme: null
IllegalArgumentException means something is wrong with an argument passed to a method. Where? Find the first location in your code:
at com.facebook.messenger.ShareToMessengerParams.<init>(ShareToMessengerParams.java:106)
at com.facebook.messenger.ShareToMessengerParamsBuilder.build(ShareToMessengerParamsBuilder.java:120)
at com.inc.nicky.messengersayit.PersonalSettings.shareFile(PersonalSettings.java:205)
...
So this tells you that on line 205 in PersonalSettings.java, there is a problem with an argument. And the problem is to do with a null URI scheme when build() is called.
At a guess, I'd say the contentUri parameter could be the problem. This value is being set earlier by Uri contentUri = Uri.parse(location);. Uri.parse(), according to the docs:
Creates a Uri which parses the given encoded URI string.
Parameters: uriString: an RFC 2396-compliant, encoded URI
A little bit of research into URIs (like help from this question) leads us to see that uriString needs to have a scheme like http:// or file:// at the start of the string.
In your case, you are calling Uri.parse with a plain filename without a scheme, resulting in the error presented to you in logcat.
Adding an appropriate scheme or using a helper function from the Uri class should help to fix the problem:
Uri contentUri = Uri.fromFile(new File(location));
