I connected the library by tutorial . It seems that everything is connected, now I want to write my own method that calls native code, which in turn will then have to call functions from the library. When I want to create a method to call the native code using the "hints" of AndroidStudio, then immediately a file is created that is circled in red.

in java

static { System.loadLibrary("speex"); } private native void initEncoder();

in C

 #include <jni.h> JNIEXPORT void JNICALL Java_com_audiorecorderclient_MainActivity_initEncoder(JNIEnv *env, jobject instance) { // TODO }

and when calling the initEncoder(); function initEncoder(); catching

  java.lang.UnsatisfiedLinkError: No implementation found for void com.audiorecorderclient.MainActivity.initEncoder() (tried Java_com_audiorecorderclient_MainActivity_initEncoder and Java_com_audiorecorderclient_MainActivity_initEncoder__)

  • It may not see the library, the gradle file contains the following lines: ndk {moduleName "speex"}? - Alexey Shtanko
  • No, I removed them, it was impossible to connect them with them, they gave out errors - Kirill Stoianov
  • @AdamLuisSean here with such a message error #error You now need to define FIXED_POINT or FLOATING_POINT - Kirill Stoianov
