我想在一个单独的进程中启动一个服务(即当我在设置中转到我的应用程序管理器然后转到运行服务时,它应该在一个单独的进程中显示我的服务).
我的Android Manifest如下:
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.timerapp.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name="com.example.timerapp.WorkerThread"
android:process="com.moizali"></service>
</application>
我在MainActivity中启动服务,所以当我杀死应用程序时,服务也会关闭.任何人都可以告诉我如何将服务作为一个不同的过程启动.
我一直在尝试过去3天在默认的android消息视图中显示图形自定义图释.我已经成功地显示了我的自定义表情符号来代替键.现在的问题是我试图在spanable字符串构建器中显示drawable.但是drawable只是没有出现在键盘上.这是迄今为止的代码:
SpannableString ss = new SpannableString(" ");
Drawable d = getResources().getDrawable(R.drawable.a);
d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
// ImageSpan span = new ImageSpan(d, ImageSpan.ALIGN_BASELINE);
ImageSpan span = new ImageSpan(d);
// ss.setSpan(span, 0, 1, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
mComposing.append(":");
mComposing.setSpan(new ImageSpan(d), 0,1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
getCurrentInputConnection().commitText(mComposing, 1);
我已经尝试了不同的方法以某种方式适合drawable但它只是不会显示在android的默认消息视图.任何帮助将受到高度赞赏.
我在Lollipop 5.0 Nexus上遇到此错误.
这就是我得到的

当我尝试使用Android的AudioRecorder类进行录制时,我收到此错误.
我使用NDK Stack来转储崩溃,我得到以下日志.

有没有人经历过这个？
我正在使用AudioTrack播放我通过UDP套接字收到的声音.我和声音一起发出很多噪音,所以我决定使用AudioManager.但是AudioManager会将声音路由更改为超出应用程序的范围.以下是我正在使用的代码.
m_amAudioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
m_amAudioManager.setMode(AudioManager.MODE_IN_CALL);
m_amAudioManager.setSpeakerphoneOn(false);
这段代码的问题在于,当我关闭应用程序并启动音乐播放器时,声音来自前置扬声器而不是后置扬声器,我不能以某种方式改变它.要解决此问题,我决定在关闭应用时添加以下行.
m_amAudioManager.setSpeakerphoneOn(true);
但是对于这条线,问题是当我接到一个电话(正常通话)时,默认情况下扬声器开启.我真的需要帮助.
我正在使用Retrofit来使用Web服务,到目前为止它很棒.但Retrofit是否提供了从URL下载视频的方法？
我查看了此链接,但@Streaming注释不再可用.复古适合图像下载

我想选择一些电子邮件地址,然后向所有人发送电子邮件.
我的代码如下:
emailIntent .putExtra(android.content.Intent.EXTRA_EMAIL,new String[]{listofemailaddresses});
emailIntent .putExtra(android.content.Intent.EXTRA_SUBJECT, "My Subject");
emailIntent .putExtra(android.content.Intent.EXTRA_TEXT, Constants.SMS_MESSAGE);
this.startActivity(Intent.createChooser(emailIntent, "Send mail..."));`
listofemailaddresses是一个字符串,其中包含以","符号分隔的所有电子邮件.但是To字段在这里总是空的.
我正在使用Dagger注入RestAdapter.Builder,我正在该函数中创建一个OkHttpClient.功能如下:

final OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setConnectTimeout(Constants.CONNECT_TIMEOUT, TimeUnit.SECONDS);

okHttpClient.setReadTimeout(Constants.READ_TIMEOUT, TimeUnit.SECONDS);
try {
okHttpClient.setCache(new Cache(mApplication.getCacheDir(), Constants.CACHE_SIZE));
} catch (final IOException e) {
LOG.warn(e.getMessage(), e);

我想知道是否可以获取仅存在于SIM卡或电话簿中的联系人.现在我正在使用以下代码来获取联系人,它甚至可以获取所有联系人以及我的Gmail和Facebook联系人.
Cursor cursor = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI, null, null, null, Phone.DISPLAY_NAME + " ASC");
if (cursor.getCount() > 0)
{
while (cursor.moveToNext())
{
PhoneBookUserEntity user = new PhoneBookUserEntity();
// Pick out the ID, and the Display name of the

user.setId(cursor.getString(cursor.getColumnIndex(BaseColumns._ID)));
user.setPhoneBookName(cursor.getString(cursor.getColumnIndex(
ContactsContract.Contacts.DISPLAY_NAME)));
if(user.getphonebookname().length() > 4)
username = user.getphonebookname();//.substring(0,4);
else
username = user.getphonebookname();//.substring(0,1);
