This is a typical stack overflow error that occurs in the accessibility service of DroidRun Portal. It can be seen from the error stack that the findAllVisibleElements method has fallen into an infinite recursive call, resulting in the exhaustion of stack space.
Problem Analysis
Causes of the error:
- Infinite recursion: The
findAllVisibleElements method continuously calls itself at line 355.
- Circular reference of UI elements: Some UI elements may have circular references in parent-child relationships.
- The
ElementNode.createId method also has a recursion problem when processing Rect.toShortString.
Impact:
- Inability to obtain UI status: The Portal service crashes and cannot normally obtain UI element information.
- Slow device response: The crash of the accessibility service may affect device performance.
- Invalid DroidRun functions: All functions that depend on the UI status will fail.
