我正在尝试使用以下代码检查 TTS 设施和语音设施的存在，但它因 starnge 错误而失败。我无法解决这个问题。我附上了 logcat 以供参考。请协助。
Java 代码：
private void checkTTSAvailability() {
Log.i("Splash", "checkTTSAvailability");
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, 1);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.i("Splash", "onActivityResult");
if (requestCode == 1) {
Log.i("Splash", "onActivityResult - 1");
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
// success, create the TTS instance
Log.i("Splash", "TTS check intent - success, : TTS presence confirrmed !");
startDragAndDrop();
}
else { // missing data, install it
PackageManager pm = getPackageManager();
Intent installIntent = new Intent();
installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
ResolveInfo resolveInfo = pm.resolveActivity(installIntent, PackageManager.MATCH_DEFAULT_ONLY);
if (resolveInfo == null) {
Log.i("DragDrop", "No voice support on your phone");
Dialog d = new Dialog(this);
d.setTitle("Alert ");
TextView tv = new TextView(this);
tv.setText("No voice support on your phone");
d.setContentView(tv);
d.show();
} else {
Dialog d = new Dialog(this);
d.setTitle("Alert ");
TextView tv = new TextView(this);
tv.setText("Installing");
d.setContentView(tv);
d.show();
Log.i("DragDrop", "Installing");
startActivity(installIntent);
}
}
}
}
}
