ほぼ2か月間間違った道を進んだ後、私は自分の間違いが何であるかを知りました。今、私は答えを見つけることができない新しい問題のペースを調整しています：ヘッドセットに接続しようとしているときにこの機能を使用する：
mBluetoothAdapter.getProfileProxy(context, mProfileListener, BluetoothProfile.HEADSET);
final BluetoothProfile.ServiceListener mProfileListener = new BluetoothProfile.ServiceListener() {
public void onServiceConnected(int profile, BluetoothProfile proxy) {
if (profile == BluetoothProfile.HEADSET) {
mBluetoothHeadset = (BluetoothHeadset) proxy;
}
}
public void onServiceDisconnected(int profile) {
if (profile == BluetoothProfile.HEADSET) {
mBluetoothHeadset = null;
}
}
};
mBluetoothHeadsetオブジェクトを初期化できません。何らかの理由で、デバッガーがonServiceConnected関数にステップインしません。
どんな助けでもありがたいです...本当に1つのシャイが必要です
詳細：Androidを再起動した後、Bluetoothを有効にする必要がありました'コードで解決：これは関数コードです：Log（ "PM.CheckForHeadSet"、 "In"）;
if (mBluetoothAdapter == null) {
Log("PM.CheckForHeadSet","BlueTooth adapter not found");
return "Error Bluetooth adapter";
}
switch (mBluetoothAdapter.getState()){
case BluetoothAdapter.STATE_OFF:
Log("PM.CheckForHeadSet.getState"," STATE_OFF");
mBluetoothAdapter.enable();
break;
case BluetoothAdapter.STATE_TURNING_ON:
Log("PM.CheckForHeadSet.getState","STATE_TURNING_ON");
break;
case BluetoothAdapter.STATE_ON:
Log("PM.CheckForHeadSet.getState","STATE_ON");
break;
case BluetoothAdapter.STATE_TURNING_OFF:
Log("PM.CheckForHeadSet.getState","STATE_TURNING_OFF");
break;
}
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
// If there are paired devices, add each one to the ArrayAdapter
if (pairedDevices.size() == 1) {
for (BluetoothDevice device : pairedDevices)
if(device.getBondState() == BluetoothDevice.BOND_BONDED){
Log("PM.CheckForHeadSet Connected to:",device.getName());
}
}
Log("PM.CheckForHeadSet ServiceListener:","In");
final BluetoothProfile.ServiceListener mProfileListener = new BluetoothProfile.ServiceListener() {
public void onServiceConnected(int profile, BluetoothProfile proxy) {
if (profile == BluetoothProfile.HEADSET) {
mBluetoothHeadset = (BluetoothHeadset) proxy;
}
}
public void onServiceDisconnected(int profile) {
if (profile == BluetoothProfile.HEADSET) {
mBluetoothHeadset = null; }
}};
if(mBluetoothHeadset == null)
Log("PM.CheckForHeadSet","mBluetoothHeadset = null");
else
Log("PM.CheckForHeadSet","mBluetoothHeadset = " + mBluetoothHeadset.toString());
if(context == null)
Log("PM.CheckForHeadSet","context = null");
else
Log("PM.CheckForHeadSet","context = " + context.toString());
if(mProfileListener == null)
Log("PM.CheckForHeadSet","mProfileListener = null");
else
Log("PM.CheckForHeadSet","mProfileListener = " + mProfileListener.toString());
if(mBluetoothAdapter.getProfileProxy(context, mProfileListener, BluetoothProfile.HEADSET) == true)
Log("PM.CheckForHeadSet.getProfileProxy","true");
else
Log("PM.CheckForHeadSet.getProfileProxy","false");
Log("PM.CheckForHeadSet","Out");
return "Set Headset";
GetProfileProxyを新しいProfileListenerの上に配置した場合（docomantaionの例のように|）、mProfileListener変数はまだnullであり、getProfileProxyはfalseを返します
そしてこれはlogcatです：
