Android KitKat(API 19) – 如何在SMS内容提供程序中写入消息,而不将其发送到非默认应用程序？

<uses-permission android:name="android.permission.READ_SMS"/>
<uses-permission android:name="android.permission.WRITE_SMS"/>

private final String SENT_SMS_CONTENT_PROVIDER_URI_OLDER_API_19 = "content://sms/sent";

ContentValues values = new ContentValues();
values.put("address",mnumber);
values.put("body",mmessagE);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODEs.KITKAT)
  mContext.getContentResolver().insert(Telephony.Sms.Sent.CONTENT_URI,values);
else mContext.getContentResolver().insert(Uri.parse(SENT_SMS_CONTENT_PROVIDER_URI_OLDER_API_19),values);

Intent intent = new Intent();
intent.setClassName("com.android.setTings","com.android.setTings.SetTings");
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_DEFAULT);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
intent.putExtra(":android:show_fragment","com.android.setTings.applications.AppOpsSum@R_944_11035@");
startActivity(intent);

SmsWriteOpUtils类使用反射访问AppOpsmanager服务的方法,以便启用/禁用非默认SMS应用程序对API Level 19(KitKat)中的SMS提供程序的写入访问.一旦设置,应用程序的访问模式将被保留,直到它被重置,或应用程序被卸载.

启用应用程序的写访问权限允许应用程序与SMS提供程序进行交互的所有标准方法,包括insert()和delete().

请注意,此类不执行API级别检查,并且仍需要WRITE_SMS权限.

import android.app.AppOpsmanager;
import android.content.Context;
import android.content.pm.PackageManager;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

public final class SmsWriteOpUtils {
    private static final int WRITE_OP_CODE = 15;

    public static Boolean isWriteEnabled(Context context) {
        int result = checkOp(context);
        return result == AppOpsmanager.MODE_ALLOWED;
    }

    public static Boolean setWriteEnabled(Context context,Boolean enabled) {
        int mode = enabled ? AppOpsmanager.MODE_ALLOWED : AppOpsmanager.MODE_IGNORED;
        return setMode(context,modE);
    }

    private static int checkOp(Context context) {
        try {
            Method checkOpMethod = AppOpsmanager.class.getmethod("checkOp",Integer.TYPE,String.class);

            AppOpsmanager appOpsmanager =
                (AppOpsmanager) context.getSystemservice(Context.APP_OPS_serviCE);
            int uid = context.getApplicationInfo().uid;
            String packagename = context.getPackagename();

            return checkOpMethod.invoke(appOpsmanager,WRITE_OP_CODE,uid,packageName);
        }
        catch (NoSuchMethodException | InvocationTargetException | illegalaccessexception E) {
            e.printStackTrace();
        }
        return -1;
    }

    private static Boolean setMode(Context context,int mode) {
        try {
            Method setModeMethod = AppOpsmanager.class.getmethod("setMode",String.class,Integer.TYPE);

            AppOpsmanager appOpsmanager =
                (AppOpsmanager) context.getSystemservice(Context.APP_OPS_serviCE);
            int uid = context.getApplicationInfo().uid;
            String packagename = context.getPackagename();

            setModeMethod.invoke(appOpsmanager,packagename,modE);

            return true;
        }
        catch (NoSuchMethodException | InvocationTargetException | illegalaccessexception E) {
            e.printStackTrace();
        }
        return false;
    }
}

使用示例

Boolean canWriteSms;

if(!SmsWriteOpUtils.isWriteEnabled(getApplicationContext())) {
    canWriteSms = SmsWriteOpUtils.setWriteEnabled(getApplicationContext(),truE);
}
...

注意：对于常规用户应用程序,这仅适用于API Level 19(KitKat).孔在以后的版本中修补.
