请求运行时权限时java.lang.StackOverflowError

Question

我创建了一个公共类PermissionManager，用于管理来自单个地方的所有权限，但通常它工作正常但在上传后显示有关崩溃分析的错误报告我无法重现，详细信息以下是提及

你有一个无限循环，我猜是由某人拒绝位置权限，并选择“永不问agan”复选框：

这将自动拒绝对“位置”权限的任何进一步请求。在您的情况下，这会成为一个大问题，因为double findtime(int Px, int Py, int Pz, int Ex, int Ey, int Ez, int Vx, int Vy, int Vz, int Cx, int Cy, int Cz, int R) { double a = (Ex*Ex+ Ey* Ey + Ez * Ez); double b = (2 * Ex*Vx + 2 * Ey*Vy + 2 * Ez*Vz); double g = Vx * Vx + Vy * Vy + Vz * Vz; double e= Ex * Px - Ex * Cx + Ey * Py - Ey * Cy + Ez * Pz - Ez * Cz; double o= Vx * Px - Vx * Cx + Vy * Py - Vy * Cy + Vz * Pz - Vz * Cz; double d= (Px - Cx)*(Px - Cx) + (Py - Cy)*(Py - Cy) + (Pz - Cz)*(Pz - Cz) - R * R; double A = o* o- g* d; double B = 2 * e*o- b* d; double C = e* e- d* a; if (A != 0) { double D = B * B - 4 *A*C; double rootD = sqrt(D); double t1 = (-1*B + rootD) / (2 * A); double t2 = (-1*B - rootD) / (2 * A); if (t1 <= 0 && t2 > 0) { return t2; } else if (t2 <= 0 && t1 > 0) { return t1; } else { return min(t1, t2); } } else { double ans = -C / B; return ans; } } 会使用PermissionManager::checkPermission()提示您使用权限对话框，该对话框会自动被拒绝，而后者会调用showDialogForPermission()。

onRequestPermissionsResult()

由于if (shouldShowRequestPermission(context, permission)) { MY_REQUESTED_DIALOG = true; showDialogForPermission(context, messageTitle, messageDetails, permission, requestCode); } else { /* THIS LINE IS STARTING THE INFINITE LOOP */ requestPermission(context, permission, requestCode); } 正在返回shouldShowRequestPermission(context, permission)，false永远不会设置为MY_REQUESTED_DIALOG，并且流程会一遍又一遍地循环。如果true中shouldShowRequestPermission() == false 和您的权限被拒绝，我的建议是退出权限流程。

onRequestPermissionsResult()

堆栈跟踪是无限循环的症状。
