android各類筆記

一.生成key

二.mac os項目變大

刪除 項目中app->build文件夾的intermediates文件夾

 

三.項目生成jar 和aar

四.android 友盟推送與阿里電商sdk同時繼承衝突

（ERROR: Dex writing phase: classes.dex has too many IDs. Try using multi-dex)

這個緣由是同時集成的友盟消息推送與阿里電商聯盟的sdk jar中有相同的類，解決方法。

將PushSDK生成.arr文件後倒入項目，分別繼承問題解決.  

路徑：

cd /Users/hangliao/Desktop/umeng_message201710181609_3.1.3a.upush/PushExample/Pushlib/build/outputs/aar/Pushlib-release.aar

 

五.xls在線轉換csv

       contentLayout=(LinearLayout)convertView.findViewById(R.id.paomadeng_linelayout);

lunbo_textview = new TextView(getActivity());
lunbo_textview.setText("12121212");
lunbo_textview.setTextSize(13);
lunbo_textview.setSingleLine(true);
//設置字體顏色

Resources resource =   getActivity().getBaseContext().getResources();
ColorStateList csl = resource.getColorStateList(R.color.white_color);

lunbo_textview.setTextColor(csl);
LinearLayout.LayoutParams lunbo_textviewLayoutParameter = new LinearLayout.LayoutParams(LinearLayout.LayoutParams    .MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    lunbo_textviewLayoutParameter.topMargin=45;
lunbo_textviewLayoutParameter.leftMargin=13;
lunbo_textviewLayoutParameter.rightMargin=1;
lunbo_textview.setLayoutParams(lunbo_textviewLayoutParameter);

contentLayout.addView(lunbo_textview);



1.app真機調試報錯

adb install -r 中出現INSTALL_FAILED_UNKNOWN_SOURCES，怎樣解決？

D:\android_code\0708\tools>adb install -r D:\work_feixun\Gallery2.apk
3030 KB/s (7663016 bytes in 2.469s)
pkg: /data/local/tmp/Gallery2.apk
Failure [INSTALL_FAILED_UNKNOWN_SOURCES] 

解決：設置->安全->未知來源（容許安裝來自未知來源的應用）。
