Romain Vimont 54dede3630 Fix startActivity() for supporting API < 30
Call the older startActivityAsUser() instead of
startActivityAsUserWithFeature() so that it also works on older Android
versions.

Romain Vimont 6a58891e13 Use current time as initial timestamp on error
If the initial timestamp could not be retrieved, use the current time as
returned by System.nanoTime(). In practice, it is the same time base as
AudioRecord timestamps.

Romain Vimont ec41896c85 Fix integer overflow for audio packet duration
The result is assigned to a long (64-bit signed integer), but the
intermediate multiplication was stored in an int (32-bit signed
integer).

This value is only used as a fallback when no timestamp could be
retrieved, that's why it did not cause too much harm so far.

Romain Vimont 4b4f045e19 Fix audio PTS by the duration of 1 sample
If the difference of PTS between two consecutive blocks of audio is less
than 1 sample, then it will be considered as non-increasing by FFmpeg
muxers having a time_base of 1/sample_rate.

Increase the PTS by 1 sample instead.

Romain Vimont a402eac7f2 Compute PTS of intermediate blocks
If several reads are performed for a single captured audio block (e.g.
if the read size is smaller than the captured block), then the provided
timestamp was the same for all packets.

Recompute the timestamp for each of them.

Romain Vimont 3bb6b0cb9f Read audio by blocks of 1024 samples
In practice, the system captures audio samples by blocks of 1024
samples.

Remplace the hardcoded value of 5 milliseconds (240 samples), and let
AudioRecord fill the input buffer provided by MediaCodec (or by
AudioRawRecorder), with a maximum size of 1024 samples (just in case).

Romain Vimont 01d785d9a3 Increase attempts to start AudioRecord
Making the shell app foreground (specific for Android 11) may take more
than 300ms on some devices, so increase the number of attempts from 3 to
5 (separated by 100ms).

Simon Chan cab354102d Create AudioRecord by reflection as a fallback
Some devices (Vivo phones) fail to create an AudioRecord from an
AudioRecord.Builder (which throws a NullPointerException).

In that case, create an AudioRecord instance directly by reflection.

The AOSP version of AudioRecord constructor code can be found at:
 - Android 11 (R):
   <https://cs.android.com/android/platform/superproject/+/android-11.0.0_r1:frameworks/base/media/java/android/media/AudioRecord.java;l=335;drc=64ed2ec38a511bbbd048985fe413268335e072f8>
 - Android 12 (S):
   <https://cs.android.com/android/platform/superproject/+/android-12.0.0_r1:frameworks/base/media/java/android/media/AudioRecord.java;l=388;drc=2eebf929650e0d320a21f0d13677a27d7ab278e9>
 - Android 13 (T, functionally identical to Android 12):
   <https://cs.android.com/android/platform/superproject/+/android-13.0.0_r1:frameworks/base/media/java/android/media/AudioRecord.java;l=382;drc=ed242da52f975a1dd18671afb346b18853d729f2>

Romain Vimont 3626d90004 Use separate audio capture code for Android 11
The code to start audio capture is more complicated for Android 11
(launch a fake popup, wait, make several attempts, close the shell
package).

Use a distinct code path specific to Android 11.

Romain Vimont 02f4ff7534 Make 3 attempts to start AudioRecord
On Android 11, a fake popup must be briefly opened to make the system
think that the shell app is in the foreground so that audio may be
recorded.

Making the shell app foreground may take some time depending on the
device, so make 3 attempts, waiting 100ms before each.

If read() returns 0, then there is no data. According to the
documentation, it happens if the buffer is not a direct buffer:
