Android SharedPreferences在不同应用模块里通信

Android源码开发，经常会遇到sharedpreference在一个模块写，在另一个模块读的情况，实现起来也很简单

在Dialer模块里写

private static final String PREFER_NAME = "share";
private static int MODE = Context.MODE_WORLD_READABLE + Context.MODE_WORLD_WRITEABLE + Context.MODE_MULTI_PROCESS;

SharedPreferences share = getSharedPreferences(PREFER_NAME,MODE);

share.putBoolean("vibratecall", true);

share.commit();

在Settings模块里读

private Context getTargetContext() throws NameNotFoundException {
return getContext().createPackageContext("com.android.dialer", Context.CONTEXT_IGNORE_SECURITY);
}

try {
SharedPreferences share = getTargetContext().getSharedPreferences(PREFER_NAME,MODE);
boolean needVibrate = share.getBoolean("vibratecall", false);
Log.v(TelephonyConnection.this, "needVibrate = "+needVibrate);
if(needVibrate){
Vibrator vbr = (Vibrator) getPhone().getContext().getSystemService(Context.VIBRATOR_SERVICE);
vbr.vibrate(300);
}
} catch (NameNotFoundException e) {
e.printStackTrace();
Log.i("callvibrate", "木有找到该包名");
}
