2 Activities Problem in Android Studio Code

Asked 2020-Nov-14 at 20:25

I'm programming a little app via Android Studio. I'm working with 2 activities. My app stops responding as soon as my first activity opens the second one (When I'm running the app through the emulator). I realized that the problem first appeared as I inserted the for loop in my second activity. But the audio output of the notes is still done in the background.

Would be very nice if you could help me here.

Here the code:

Asked 2020-May-03 at 16:34

I am unable to install pycodec2. I first git cloned the pycodec2 repo. Then cloned and installed codec2 repo inside it. I had to edit a few paths in pycodec2, but after so much tinkering I am unable to get the pycodec2 running. Does anybody have experience installing pycodec2 and can share the steps?

Thanks!

You will need to install either the codec2 libraries, and/or the development files, depending on whether or not it is using them to run, or to compile.

On Ubuntu you can achieve this with:

In case anyone has problems with this in the future, the destroy recordable surface code in the previous format is running upon return and intermittently. I moved it down to the code that executes on pause when the app surface is destroyed and it works now.

Install codec2

Listen to Codec 2:.
Install packages (Debian/Ubuntu): sudo apt install git build-essential cmake Fedora/RH distros: sudo dnf groupinstall "Development Tools" "C Development Tools and Libraries" sudo dnf install cmake
Build Codec 2: git clone https://github.com/drowe67/codec2.git cd codec2 mkdir build_linux cd build_linux cmake .. make
Listen to Codec 2: cd codec2/build_linux ./demo/c2demo ../raw/hts1a.raw hts1a_c2.raw aplay -f S16_LE ../raw/hts1a.raw aplay -f S16_LE hts1a_c2.raw
Compress, decompress and then play a file using Codec 2 at 2400 bit/s: ./src/c2enc 2400 ../raw/hts1a.raw hts1a_c2.bit ./src/c2dec 2400 hts1a_c2.bit hts1a_c2_2400.raw which can be played with: aplay -f S16_LE hts1a_c2_2400.raw Or using Codec 2 using 700C (700 bits/s): ./src/c2enc 700C ../raw/hts1a.raw hts1a_c2.bit ./src/c2dec 700C hts1a_c2.bit hts1a_c2_700.raw aplay -f S16_LE hts1a_c2_700.raw
If you prefer a one-liner without saving to files: ./src/c2enc 1300 ../raw/hts1a.raw - | ./src/c2dec 1300 - - | aplay -f S16_LE
Or you can use your microphone and headphones to encode and listen to the result on the fly: br=1300; arecord -f S16_LE -c 1 -r 8000 | ./src/c2enc $br - - | ./src/c2dec $br - - | aplay -f S16_LE -
