Root Cause

RenderScript kernel uses an Element type that is not supported or mismatched with allocation data type.

中文

RenderScript 内核使用了不受支持的 Element 类型，或与分配数据类型不匹配。

Workarounds

  1. 90% success Ensure Element type in .rs kernel matches Allocation type in Java. Example: In Java, Allocation.createTyped(rs, Type.createXY(rs, Element.F32(rs), w, h)). In .rs, use float *input = rsGetElementAt_type(inputAlloc, x, y); 
    Ensure Element type in .rs kernel matches Allocation type in Java. Example: In Java, Allocation.createTyped(rs, Type.createXY(rs, Element.F32(rs), w, h)). In .rs, use float *input = rsGetElementAt_type(inputAlloc, x, y);
  2. 80% success Migrate from RenderScript to Android NDK or Vulkan Compute for better support. Rewrite kernels in C++ or GLSL.

Dead Ends

Common approaches that don't work:

  1. Change all Element types to F32 in the .rs file 70% fail

    If allocation data is not float, conversion fails silently; may cause wrong results or crashes.

  2. Use deprecated rsGetElementAt() instead of rsGetElementAt_type() 65% fail

    Deprecated in API 23+; still compiles but may cause undefined behavior or slower performance.
