Answer 1

请参阅http://android-developers.blogspot.in/2013/10/getting-your-sms-apps-ready-for-kitkat.html

根据文档" Android 4.4(KitKat)使现有API公开,并添加了默认SMS应用程序的概念,用户可以在系统设置中选择. "

在您的代码中,您应该将其作为单独的案例处理

         Intent smsIntent;
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            String defaultSmsPackageName = Telephony.Sms.getDefaultSmsPackage(context); //Need to change the build to API 19
            smsIntent = new Intent(Intent.ACTION_SEND);
            smsIntent.setType("text/plain");
            smsIntent.putExtra(Intent.EXTRA_TEXT,"content");
            //if no default app is configured, then choose any app that support this intent.
            if (defaultSmsPackageName != null) {
                smsIntent.setPackage(defaultSmsPackageName);
            }
        } else {
            smsIntent = new Intent(Intent.ACTION_VIEW);
            smsIntent.setType("vnd.android-dir/mms-sms");
            smsIntent.putExtra("address", phoneNumber);
            smsIntent.putExtra("sms_body","body");
        }

Answer 2

低于kiktat

public static final String getDefaultSmsPackage(Context context){
    String defApp = Settings.Secure.getString(context.getContentResolver(), "sms_default_application");
    PackageManager pm = context.getApplicationContext().getPackageManager();
    Intent iIntent = pm.getLaunchIntentForPackage(defApp);
    ResolveInfo mInfo = pm.resolveActivity(iIntent,0);
    return mInfo.activityInfo.packageName;
}

高于或等于kitkat

Telephony.Sms.getDefaultSmsPackage(this)
