###Andorid Meeting SDK: We are facing a recurring **ANR (Application Not Responding)** issue related to keystore decryption while using the Zoom Android SDK. From the stack trace, it appears that `com.google.crypto.tink.integration.android.AndroidKeystoreAesGcm.decryptInternal` is making a **blocking Binder call** on the main thread, eventually leading to an ANR. Below is the relevant part of the trace: ```auto #00 pc 0x0000000000085c6c /apex/com.android.runtime/lib64/bionic/libc.so (syscall+28) #01 pc 0x0000000000201990 /apex/com.android.art/lib64/libart.so (art::ConditionVariable::WaitHoldingLocks+136) #02 pc 0x00000000005ec884 /apex/com.android.art/lib64/libart.so (artJniMethodEnd+120) #03 pc 0x000000000068f80c /apex/com.android.art/lib64/libart.so (art_jni_method_end+12) at android.os.BinderProxy.transactNative (Native method) This Binder call may be taking too long, causing the main thread to wait, and triggering the ANR.
