Ho un'applicazione complessa che crea più oggetti Bitmap e li utilizza per creare BitmapDrawables. So che questa potrebbe essere una domanda difficile a cui rispondere, ma qualsiasi aiuto nell'indirarmi nella giusta direzione sarebbe molto apprezzato. Ho eseguito test sull'assegnazione della memoria e sono uscito per lo più a mani vuote. ... Qualche idea su cosa potrebbe causare questo?IllegalArgumentException Surface.nativeLockCanvas, Choreographer, BufferQueue

…
Non stai esaurendo la memoria. L'errore si verifica nel primo paio di righe di registro: BufferQueue si trova in uno stato negativo, rifiutando i tentativi di accodamento di un buffer. Quindi il buffer è ancora ufficialmente "ritirato" e quando lockCanvas() prova a dequeue un altro, BufferQueue sta dicendo no. Sembra che la causa principale sia il passaggio di una barriera NULL a queueBuffer(). Non sono sicuro di cosa potrebbe causare quello. – fadden
Grazie @fadden ... [Ecco] (https://android.googlesource.com/platform/frameworks/native/+/708cc79/libs/gui/BufferQueue.cpp) dove potrebbe essere il recinto nullo, io sono ancora lavorando alla caccia di questo. – ChrisVollo
Mi chiedo se abbia qualcosa a che fare con il dispositivo o la versione di Android che sto usando. Ho cambiato dispositivi e versioni di Android e non sono stato in grado di riprodurre il problema. – ChrisVollo
