二 拆座、問題定位
????從log中看主巍，01-19 02:11:25.328? 1777? 1777 E AndroidRuntime: android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity? context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?
? ? ?發(fā)現(xiàn)，Context中有一個(gè)startActivity方法挪凑，Activity繼承自Context孕索，重載了startActivity方法。如果使用Activity的startActivity方法岖赋，不會(huì)有任何限制，而如果使用Context的startActivity方法的話瓮孙，就需要開啟一個(gè)新的的task唐断，遇到這個(gè)異常，是因?yàn)槭褂昧薈ontext的startActivity方法杭抠。解決辦法是脸甘，加一個(gè)flag。
代碼：
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK );
這樣就可以在新的task里面啟動(dòng)這個(gè)Activity了偏灿。
加了之后發(fā)現(xiàn)還是不行丹诀，
繼續(xù)看代碼
Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
? ? ? ? intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
? ? ? ? intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
? ? ? ? intent.setType(mFileType);
? ? ? ? mcontext.startActivity(Intent.createChooser(intent, mcontext.getString(R.string.edit_bluetooth)));
這塊邏輯需要完善一下。
Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
? ? ? ? intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
? ? ? ? intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
? ? ? ? intent.setType(mFileType);
? ? ? - ?//mcontext.startActivity(Intent.createChooser(intent, mcontext.getString(R.string.edit_bluetooth)));
? ? ? + ?Intent sendIntent = Intent.createChooser(intent, mcontext.getString(R.string.edit_bluetooth));
? ? ? ?+ if (Build.VERSION.SDK_INT > Build.VERSION_CODES.O_MR1) {
? ? ? ? + ? ?sendIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
? ? ? ?+ }
? ? ? ?+ mcontext.startActivity(sendIntent);
三翁垂、搞定铆遭。
