Hi @tbruyelle, I have the same crash happening when requesting an array of permissions, like this:
protected void requestPermission(final PermissionListener listener, String... permissions) {
ArrayList<String> permissionsList = new ArrayList<>();
for (String permission : permissions) {
if (!getPermissionsInstance().isGranted(permission)) {
permissionsList.add(permission);
}
}
int required = permissionsList.size();
if (required > 0) {
getPermissionsInstance().request(permissionsList.toArray(new String[required]))
.subscribe(new Observer<Boolean>() {
@Override
public void onSubscribe(Disposable d) {
}
@Override
public void onNext(Boolean aBoolean) {
listener.granted(aBoolean);
}
@Override
public void onError(Throwable e) {
listener.granted(false);
}
@Override
public void onComplete() {
}
});
} else {
listener.granted(true);
}
}
And here's the stack trace:

这是就一个bug 我也遇到了
Attempt to invoke virtual method 'android.os.Handler android.app.FragmentHostCallback.getHandler()' on a null object reference，
我目前用的这个版本：
api 'com.tbruyelle.rxpermissions:rxpermissions:0.9.4@aar'
这个问题解决了吗？
