[android-developers] Re: How to integrate in app billing in android

[jtoolsdev]

There are some good blog articles online with concise information.  You can 
fill in the rest by reading Google's documentation though I wouldn't say 
that documentation is Google's strong point.

[android-developers] Re: Audio recording problem - fake sample rate

[Julian Bunn]

If you are only getting 8000 sps then even with interpolation to 44100 you 
would never see any signal above 4000Hz in an FFT, right? Are you windowing 
the FFT?

If there are truly problems like this with the audio firmware on the LG G3 
and Nexus 7, I haven't heard any reports from my users about them. That's 
not to say there can't be an issue, of course :-) If I were you, I would 
obtain a cheap used G3 on Ebay to test with.

 Make sure you are sizing the buffers correctly i.e. respecting the

 believe the system will drop you down to 8kHz sample rate, which is what 
 you are seeing (I think?).

[android-developers] High speed camera capture

[Joshua Parrish]

Hello all,

I'm doing my best to develop an app for high-speed camera capture. 
Unfortunately, it's difficult to work with  
createConstrainedHighSpeedCaptureSession since there are no samples 
available anywhere. Would it be possible for this community to come up with 
a small set of sample code?

For instance, there is a 
https://github.com/googlesamples/android-Camera2Video, but changing it to 
contain a high speed request is a bit confusing. Where I'm having trouble 
is specifically calling the camera requests. One must create a list, 
instead of using the request builder due to the need to use 
setRepeatingBurst. That said I run into several issues. One being that the 
createConstrainedHighSpeedCapture is supposed to produce a 
CameraConstrainedHighSpeedCaptureSession 
; but I don't see how to do that since createConstrainedHighSpeedCaptureSession 
actually produces a CameraCaptureSession.

Basically, all I'm asking for is sample code for:

createConstrainedHighSpeedCaptureSession

 with an onConfigured callback

inside the onConfigured one needs to use createHighSpeedRequestList and 
setRepeatingBurst



If a sample for just that piece could be created I would be very 
appreciative.

It's seem unable to get MAC address in android 6. Without 
WifiInfo.getMacAddress() and the BluetoothAdapter.getAddress() can we have 
an other way to get MAC address programmatically of local device.

Re: [android-developers] Help me get this code working!!

[Chuck Crisler]

The error says it all and is clear. The class ProcessRegister *MUST*
contain a method doinBackground. This is simple Java. Read about abstract
classes/interfaces and you will understand.

Re: [android-developers] RelativeLayout as a child of CoordinatorLayout

[Angel Todorov]

hey,

Thanks for the feedback. I'm setting the scroll flags and scroll behaviors, 
here's my code (below). The issue with AppBarLayout as a first child is 
that whenever I set it inside of a relative layout, which is a child of the 
CoordinatorLayout, the scrolling behavior doesn't work. I guess I wasn't 
clear enough - it should be somewhere in the direct children of the 
CoordinatorLayout, if it's a child of a child, the coordinator layout 
doesn't pick it up.

My issue is not with the scrolling behavior - that works perfectly fine. my 
issue is that the content is overlapped by the app bar. The only way to fix 
this is to use a relative layout and set layout_below, but then the 
scrolling behavior stops working.


http://schemas.android.com/apk/res/android;
xmlns:app="http://schemas.android.com/apk/res-auto;
xmlns:tools="http://schemas.android.com/tools;
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/coordinator"
android:fitsSystemWindows="true"
tools:context="com.example.todorov.myapplication.MainActivity">















Here is content_matches.xml:


http://schemas.android.com/apk/res-auto;
xmlns:android="http://schemas.android.com/apk/res/android;
android:id="@+id/swipe_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:direction="both">

http://schemas.android.com/apk/res/android;
android:id="@android:id/list"
android:layout_width="wrap_content"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:cacheColorHint="#"
android:layout_height="wrap_content"/>



I've also tried moving the list view outside of the SwipyRefreshLayout - 
didn't change anything. Also want to clarify that i am setting the 
following in code, so that I don't have to use a RecyclerView or another 
view that supports nested scrolling - because the ListView on its own 
doesn't support nested scrolling, and coordinator layout's scrolling 
behavior expects a content view which supports nested scrolling:


listview.setNestedScrollingEnabled(true);

ViewCompat.setNestedScrollingEnabled(listview, true);



Thanks again,
Angel

Re: [android-developers] RelativeLayout as a child of CoordinatorLayout

[Angel Todorov]

Found the issue,

app:layout_behavior="@string/appbar_scrolling_view_behavior"


should be set on the SwipyRefreshLayout, not on the ListView.
