我試圖從Activity訪問InputMethodService,我遇到了權限問題.這適用于自定義鍵盤應用.

我想要實現的是將在Activity中創建的文本綁定回InputMethodService. Activity從InputMethodService打開,然后從Activity,我嘗試啟動服務(這可能是問題.這是我如何從InputMethodService打開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);

}

這是我嘗試與Activity中的InputMethodService進行通信的地方：

@Override

public void onCreate(Bundle bundle){

super.onCreate(bundle);

setContentView(R.xml.keyboard);

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

}

這是我的清單文件：

package="com.my.package">

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

這是我的堆棧跟蹤：
