我试图从Activity访问InputMethodService,我遇到了权限问题.这适用于自定义键盘应用.

我想要实现的是将在Activity中创建的文本绑定回InputMethodService. Activity从InputMethodService打开,然后从Activity,我尝试启动服务(这可能是问题.这是我如何从InputMethodService打开Activity：

@Override public void onStartInputView(EditorInfo attribute, boolean restarting) {

super.onStartInputView(attribute, restarting);

Intent intent = new Intent(this, MyKeyboard.class);

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);

context.startActivity(intent);

}

这是我尝试与Activity中的InputMethodService进行通信的地方：

@Override

public void onCreate(Bundle bundle){

super.onCreate(bundle);

setContentView(R.xml.keyboard);

startService(new Intent(this, MyService.class));

}

这是我的清单文件：

package="com.my.package">

android:permission="android.permission.BIND_INPUT_METHOD">

这是我的堆栈跟踪：
