Isn't automatically granted when you request the BODY_SENSORS permission. 1 Answer Sorted by: 0 I think that the problem is the tone you used: TONECDMAONEMINBEEP is a beep of duration 400 ms ( link) You should use a beep (you can find some on the page I linked) that is continuous or lasts at least 5000 ms. Class Overview This class provides methods to play DTMF tones (ITU-T Recommendation Q.23), call supervisory tones (3GPP TS 22.001, CEPT) and proprietary tones (3GPP TS 31.111). When your app targets Android 12 (API level 31) or lower, background access NOTE: The latest version may not be available for all platforms. The Android 21 AudioTrack API provides a call to control the volume, allowing to support a sound envelope that is not encoded int the data. Adjust audio frequency and device’s volume. Pick up a note from the note list with corresponding frequency. Design a beautiful user interface using Android best practices. Change frequency slider range from the lowest to the highest. Advanced yet easy-to-use frequency generator app. Android Only instantiate ToneGenerator if necessary. Tone Generator main features: Clean and neat design with a fresh and intuitive interface.
