报错信息：Dumping memory, app will freeze. Brrr

点击查看leaks小黄标,看到报错信息：

java.lang.UnsupportedOperationException: Could not find char array in java.lang.String@334750520 (0x13f3e338)

查看我本地的集成信息：

//leakcanary for memory leak

debugImplementation'com.squareup.leakcanary:leakcanary-android:1.5'

releaseImplementation'com.squareup.leakcanary:leakcanary-android-no-op:1.5'

testImplementation'com.squareup.leakcanary:leakcanary-android-no-op:1.5'

原因是我leakcanary集成版本过低，推荐使用1.5.4或者1.6版本

//leakcanary for memory leak

debugImplementation'com.squareup.leakcanary:leakcanary-android:1.6'

releaseImplementation'com.squareup.leakcanary:leakcanary-android-no-op:1.6'

testImplementation'com.squareup.leakcanary:leakcanary-android-no-op:1.6'

修改以后重新运行，一切OK，能成功检测到内存泄漏。
